麻豆影音 will establish an independent technology holding company commercialize promising technologies within the university.An inauguration ceremony for the 麻豆影音 Technology Holding Company was held at Yeonam Hall in the afternoon of August 5, 2021. President of 麻豆影音 Park Hyung-ju and Head of Industry-Academia Cooperation Kwon Yong-jin, Director of the Research Institute for Innovative Medicine at 麻豆影音 Medical Center Kim Cheol-ho, and other university officials were present. It was also attended by Kim Sun-yong, Standing Director and Park Jae-ho, Executive Director of Administrative Affairs at the Daewoo Educational Foundation. The ceremony began with a report presented by Kwon Yong-jin, Head of Industry-Academia Cooperation, on progress related to foundation of the company, congratulatory remarks by President Park Hyung-ju, an address by Director Kim Cheol-ho, and unveiling of the signboard.The company completed establishment and business registration in July this year with approval of the Ministry of Education. As a university technology company based on the Education Ministry鈥檚 Industrial Education Enhancement and Industry-Academia-Research Cooperation Promotion Act, 麻豆影音 became the 76th technology holding company among universities in Korea. The CEO of the university鈥檚 independent technology holding company is Kwon Yong-jin, Head of Industry-Academia Cooperation, while Park Jang-ho, Deputy Head of Industry-Academia Cooperation, and Director Kim Cheol-ho will serve as directors, and Shim Gyu-cheol, Executive Director of Planning, will serve as auditor.Through establishment of this company, the school will be more active in discovering excellent technology, supporting the establishment of technology-based subsidiaries, and investing in promising venture companies. The goal is to establish a virtuous cycle of income generated through technology commercialization, which is then reinvested in R&D. In particular, the school plans to support society and companies as it leads technological innovation through swift commercialization, rather than keeping outstanding R&D achievements within the university.鈥淩ather than pursuing research that remains inside the walls of a laboratory, 麻豆影音 is seeking to contribute to our community by undertaking research that is needed by businesses and society,鈥� said President Park, adding, 鈥淲e will build a framework around this technology holding company and work to achieve coexistence and win-win growth with N4U Tech Holding Inc., where we utilize our existing expertise in collaborating with other universities.鈥淟eading hospitals overseas are earning significant revenue through technology commercialization, technology marketing, and technology start-ups,鈥� pointed out Director Kim Cheol-ho, who added, 鈥淎s of 2019, we have secured considerable competitiveness in this field, ranking first in the country in terms of the number of technology transfers and resulting revenue. We will develop an industry-university-research convergence R&D center to be established on the site in front our nursing hospital, which will add to our competitive edge.鈥漊niversity technology commercialization refers to commercialization of the outcomes of university research activities through technology transfer and technology-based startups. Technology developed at the university can be transferred to a company or institution, or the technology holding company can commercialize the technology directly or through a subsidiary. Through successful commercialization, universities can maximize the benefits of research findings, thereby contributing to enhancement of corporate and national competitiveness and job creation. It will also diversify the school鈥檚 revenue sources.麻豆影音 systematically supports the entire commercialization process for excellent patent-based technologies, from research planning to intellectual property creation, technology transfer and start-ups, through an organization dedicated to technology commercialization, professional human resources, a joint technology holding company and an independent technology holding company. As a result of these efforts, the school has seen a steep rise in performance of technology commercialization over the past five years, recording KRW 3.35 billion in technology transfer revenue in 2020, ranking 7th in the nation.

An 麻豆影音 research team has developed a silicon semiconductor-based high-sensitivity infrared photodetector. The technology will be applied to a variety of fields that require high-sensitivity and high-efficiency infrared sensors, such as autonomous vehicles, solar cells, and medical diagnostic devices.Prof. Seo Hyung-tak (Dept. of Materials Science Engineering, Graduate School Department of Energy Systems Research) of 麻豆影音 announced his team鈥檚 success in developing a high-performance silicon-based infrared light sensing device using flexoelectricity that is formed when the semiconductor crystal structure is strained. The related study was published in the online edition of Small Methods (IF=14.188), an international journal in the nano field, under the title, 鈥淐ontrollable, Self-Powered, and High-Performance Short-Wavelength Infrared Photodetector Driven by Coupled Flexoelectricity and Strain Effect鈥� on July 19, 2021. The thesis was featured on the issue鈥檚 front cover. Prof. Mohit Kumar (Graduate School Department of Energy Systems Research) and Prof. Park Ji-yong (Department of Physics, Graduate School Department of Energy Systems Research) took part in the research as first authors.Optical sensors based on the photoelectric effect that converts light into electrical signals (a method that detects photocurrent by the movement of electrons and holes formed by light) are essential part to the utilization of new and renewable energy, smartphones, the Internet of Things (IoT), and optical communication. Infrared light detection has the widest application and is used not only for thermal imaging in the medical field and night vision but also as a front sensor for autonomous vehicles and object movement detection. Although there are various operating principles in an optical sensor for detecting infrared light, the method using the photoelectric effect generated by direct absorption of infrared light shows the highest sensitivity. This method can also have high value-added applications. However, in order to manufacture such a photoelectric effect, the band gap of the light-absorbing semiconductor (minimum energy required for a semiconductor material to absorb light) must be lower than the infrared light energy. For this reason, gallium arsenide and other compound semiconductor devices have been the main choice so far. However, such compound semiconductor devices are very expensive, have low detection sensitivity in the infrared region, and are limited in performance.麻豆影音's research team focused on silicon, which had not been used as an infrared sensing material before. Applying flexoelectricity to the silicon material (effectively changing the electrical properties due to local deformation of the material, which causes a bandgap change) resulted in a strain effect (elasticity change to the semiconductor crystal structure caused by external stress and other factors, resulting in a change in physical properties) suitable for the semiconductor crystal structure, and the research team discovered it could significantly reduce bandgap energy to the same as or lower than infrared light energy. The research team used this to identify the light detection principle that maximizes optical response in the infrared region and succeeded in developing an optical sensor structure.The research team used a gold probe tip to sequentially apply micropressures of a few micro-Newtons in size to a diameter range of 960 micrometers to induce a sharp decrease in bandgap energy. Through this, it was possible to obtain an excellent device with high sensitivity, detection rate, and response rate to the light of infrared wavelengths using only a silicon semiconductor. This performance is superior to the conventional commercially-available infrared detection device.In particular, the research team used an alternating photocurrent in the photosensor to drive the device, using the photoelectric effect to negate the need for external power supply through absorption of infrared incident light that quickly turns off and on repeatedly. The detection speed of the device developed by the research team is 100 microseconds (0.1 msec), enabling high-speed detection, and using an atomic force microscope, it was confirmed that the same flexoelectricity effect-based infrared detection can be implemented at a size of 30 nanometers.鈥淭here is an important academic and technical significance in that we achieved infrared detection with an ultra-high sensitivity that was previously impossible with general-purpose silicon (Si) material widely used for sensors and integrated circuits,鈥� said Prof. Seo. He further explained, 鈥淚f applied, it will be possible to integrate a high-speed, high-sensitivity infrared detection device into an existing silicon integrated circuit, which can result in a low-cost, high-performance IoT sensor.鈥漈his research was carried out with the support of the Mid-Career Researcher Program and Young Researcher Program hosted by the Korean Ministry of Science and ICT and the National Research Foundation (NRF).

A research team led by Profs. Kim Jong-hyun and Kwon Oh-pil has successfully developed a high-performance gas sensor using an organic semiconductor. This will boost the electrical and optical gas detection capability of organic semiconductors and is expected to be utilized as a next-generation, high-sensitivity sensor to detect toxic gases.Profs. Kim Jong-hyun and Kwon Oh-pil (Department of Applied Chemistry & Biological Engineering and Graduate School of Molecular Science and Technology) and a research team at the Ulsan National Institute of Science and Technology (UNIST) School of Energy and Chemical Engineering (ECHE) jointly announced development of the gas-detecting sensor.Related research was published in the online edition of Advanced Functional Materials (IF: 18.808) an international journal in materials, under the title, 鈥淪trategic Approach for Enhancing Sensitivity of Ammonia Gas Detection: Molecular Design Rule and Morphology Optimization for Stable Radical Anion Formation of Rylene Diimide Semiconductors鈥� on July 27, 2021.Profs. Kim Jong-hyun (photo left) and Kwon Oh-pil (photo right) of 麻豆影音 and Prof. Sang-kyu Kwak of UNIST took part in the research as corresponding authors, while Oh Byoung-min and Park Seong-ha, students at 麻豆影音 Graduate School Department of Molecular Science & Technology, took part as first authors.Ammonia (NH3) gas, a volatile organic compound, is a highly toxic chemical. Inhalation of high concentrations for long periods of time can result in headache, nausea, coughing, difficulty breathing, and other reactions. A variety of studies have been carried out on the development of high precision detection technology due to the change in resistance of semiconductor materials. However, conventional inorganic semiconductors involve highly complicated manufacturing process, rendering elements of the sensors as very expensive. In contrast, organic semiconductor materials are limited in terms of detection function and detection selectivity.The research team focused on ammonia gas and the organic semiconductor material based on rylene, which can selectively formulate stable radical anion. It discovered that when rylene-structured organic semiconductor material is exposed to ammonia gas, the intramolecular transfer charge reaction formulates stable radical anion and results in amplified electric current value and changes in light absorption. The research team utilized this to develop a high-performance gas sensor that can detect amounts of ammonia gas as tiny as 200ppb (parts per billion), while at the same time amplifying electric current to 1700% from ammonia gas.The research team also verified the principle of efficient charge transfer reaction that occurs between ammonia gas molecules and rylene organic semiconductor molecules using quantum computation and also proposed the principles of sensor and material design. 鈥淭he organic semiconductor material proposed in this study has a very simple combination process and even the tiniest amount of ammonia gas can create an amplified electric current signal through radical anion reaction,鈥� said Prof. Kim. 鈥淭his will allow us to overcome cost and detection limitations, which are issues in conventional gas sensors, and resolve the related problems.鈥� He added, 鈥淭he material we have developed will enable the development of high-sensitivity ammonia gas sensors that are also competitively priced.鈥漈his research project was sponsored by the National Research Foundation (NRF) Research Facility Establishment Program (Molecular Science & Technology Research Center (MSTRC)), Basic Research in Science and Engineering (Mid-Career Researcher Program), and the International Cooperation and Leading Research Center Program (Functional Crystallization Center). <Principle of stable radical anion formation using rylene organic semiconductors and performance of high-sensitivity ammonia gas sensor using this principle><July 27, 2021 online issue of Advanced Functional Materials >

麻豆影音 has transferred color-changing technology to detect hydrogen leakage to a company in a related field. The technology will create significant momentum in the hydrogen economy and safety.This technology was developed by a research team led by Prof. Seo Hyung-tak, and through a technology transfer agreement, generated more than KRW 2.5 billion in income. This is the largest technology transfer project in the non-bio sector for 麻豆影音 since the university鈥檚 establishment.The technology transfer agreement ceremony held in Yulgok Hall on July 27, 2021 was attended by 麻豆影音鈥檚 President Park Hyung-ju, CEO of Daehyun ST Co., Ltd. Eom Ju-heung, Prof. Seo (Dept. of Materials Science and Engineering, Graduate School Department of Energy Systems Research) of 麻豆影音, and other participants from both institutions.This color-changing technology is a high-performance, high-precision sensor that can measure hydrogen concentrations with great precision, which is essential to safety in the use of hydrogen. Highlighted as a next-generation green fuel source, hydrogen is increasingly being applied to new industrial sectors. However, safety issues arising from its properties have always been a stumbling block. Since hydrogen has no color, is odorless and light weight, the risk of undetected leakage is high, and can result in combustion.This sensor technology is comprised of a liquid combination method and semi-conductor deposition method allowing multi-angle sensor processes to be constructed and customized for different purposes and mass production in various application fields.Existing conventional hydrogen detection requires a power supply, which can lead to hydrogen combustion from static electricity, and can only be installed in limited places. This new sensor is gaining wide recognition as a distinct technology in hydrogen leak detection as it primarily uses a chemical color-changing method, which enables the intuitive identification of hydrogen leaks at the starting point (without power supply). It also involves a multi-detection method which uses electrical signals for remote monitoring.The research team has also acquired numerous patents in source material technology for the hydrogen sensor to enhance its reliability. One of the original technologies it developed is nano material protection layers to increase material reliability, which is an issue with today鈥檚 hydrogen sensors.Daehyun ST plans to utilize this technology to offer hydrogen sensors to hydrogen charging stations and hydrogen automobiles. Building from this base, Daehyun ST expects to increase sales revenues not only in the domestic market but also overseas, including in Germany, Japan, and the United States.The transferred technology is particularly significant because it is a base technology fundamental to the Act on the Promotion of Hydrogen Economy and Hydrogen Safety Management (鈥淗ydrogen Safety Act鈥�), which will come into effect in February 2022. The Hydrogen Safety Act legally institutionalizes a hydrogen safety device for systemic promotion and safety management of the hydrogen industry. With this, 麻豆影音 has secured a foothold to position itself as a pioneering institution in cutting-edge technology.麻豆影音 recorded earnings of KRW 3.35 billion from last year鈥檚 technology transfers, ranking seventh among universities nationwide. Earnings from technology transfers have been rising for five years. This is an amount paid by a company seeking to utilize the R&D results by an 麻豆影音 research team and to acquire the relevant intellectual property rights. It is a major source of revenue from industry-academia cooperation and an indicator of the university鈥檚 leading research capacity. 麻豆影音 operates a technology commercialization process for all periodic cycles that enables the results of its research teams to be widely utilized by businesses and society. It is committed to the commercialization of technology. Prof. Seo鈥檚 research team built the foundation for successful commercialization of this technology, and was selected for the Project to Support Mid & Large-scale Growth of the Research Industry under the Commercializations Promotion Agency for R&D Outcomes, itself under the Ministry of Science and ICT.* Photo: From left, Eom Ju-heung, CEO of Daehyun ST Co., Ltd., Prof. Seo Hyung-tak and President Park Hyung-ju of 麻豆影音.

A joint research team from 麻豆影音 has developed a catalyst response technology that can produce hydrogen and carbon using methane, the main component of city gas, or natural gas. This is a cutting-edge energy technology that can concurrently mass produce green, affordable hydrogen fuel and high purity, high value-added carbon.The joint research team, led by Prof. Seo Hyung-tak (Dept. of Materials Science and Engineering, Graduate School Department of Energy Systems Research) and Prof. Kim Yu-kwon (Chemistry, Graduate School Department of Energy Systems Research) announced the development of technology to produce hydrogen gas and solid carbon directly converted from methane using a bubble column reactor injected with molten liquid alloy catalysts and zirconia. Their achievement was published in the online edition of Chemical Engineering Journal (IF=13.273) on July 7, 2021 under the title, 鈥淓nhanced Efficiency in CO2-free Hydrogen Production from Methane in a Molten Liquid Alloy Bubble Column Reactor with Zirconia Beads.鈥� Lee Young-jae, a doctoral student at 麻豆影音, and Dr. Noh Yong-gyu took part as first co-authors, and another doctoral student, Kim Jin-a, and Prof. Shankara Kalanur also joined.Hydrogen, a clean fuel that emits water after use, has recently gained recognition as a next-generation energy source and is increasingly applied to diverse industrial fields. Mass production of hydrogen as fuel is commonly achieved by reforming fossil fuels, but the process emits CO2 that is nine times greater than the weight of hydrogen thereby produced.Due to this and other reasons, research has recently been active in photoelectrochemical water splitting technology using electricity or solar energy towards reducing emission of CO2, a major greenhouse gas. However, barriers have existed to these efforts as the unit cost of production has been at least five to six times the cost of reforming fossil fuels, and it could not be mass produced. Therefore, development of a way to mass produce hydrogen in an affordable and CO2-free manner is urgently needed if we are to realize a hydrogen economy, with hydrogen energy as a completely clean fuel.The 麻豆影音 research team focused on methane gas (CH4), a major component in city and natural gas. When methane gas undergoes a pyrolysis process using solid catalysts at temperatures greater than 1000鈩�, it produces hydrogen gas and solid carbon. The solid carbon thereby produced could not be commercialized previously as it becomes deactivated. When solid carbon accumulates on the surface of the catalyst, it ultimately prevents the chemical reaction of methane gas there, as a result of which its reaction activity rapidly disappears.To address this limitation, researchers have recently turned their attention to the use of low-melting liquid metal (LM) alloy catalysts (liquid metal catalyst combining low-melting metals, such as tin, and high-melting metals, such as nickel, which are high catalyst activation). In other words, direct molten catalyst methane conversion technology injects methane gas into molten liquid metal alloy to produce hydrogen. At the same time, flotation and reaction are maintained due to the difference in carbon layer density on the surface of the liquid catalyst while also producing solid carbon.The joint research team developed a new method, based on this direct molten catalyst methane conversion technology, to discover that maximizing the surface area of the boundary between methane gas and liquid catalyst by reducing the residence time of methane gas inside the liquid catalyst and size of the methane gas bubble in the methane decomposition reaction using liquid catalysts is a critical factor in enhancing reaction efficiency. The research team developed a new reactor structure by additionally injecting zirconia (a mixture of zirconium and oxygen (ZrO2) which has a high melting point, is not easily decomposed, and is in a white crystalline form at room temperature) to the liquid catalyst in the reactor to minimize the size of the methane bubble and complicate the gas flow channel, which increased gas residence time.The adoption of a new reactor structure resulted in a high hydrogen conversion rate (about 37% methane at 985鈩�, lower than the existing temperature of at least 1000鈩�), and strong reaction durability as catalyst activity increased even after a long production period of more than 150 hours. In general, methane thermal decomposition reaction at 1000鈩� or lower lowers the cost of thermal energy in accordance with reactor quality, but it also resulted in a rapid decrease in conversion rate. The Ajou research team overcame this stumbling block to record the highest conversion rate and continuous reaction at low temperature. The carbon produced using this new method was in a form that is high purity and high value-added (carbon nanotube and fiber filament). Such carbon can be used in batteries and fuel cells. This new development taps into the potential not only for environmentally-friendly mass production of hydrogen but also high-applicability carbon materials.鈥淭he existing hydrogen production methods using fossil fuels will inevitably undergo a rise in price due to trends toward stronger regulations on CO2 emissions,鈥� said Prof. Seo. 鈥淭his research is significant in that it has opened up a new green and affordable path of mass production of hydrogen.鈥滺e also added, 鈥淚t can be remarkably economical if the carbon produced simultaneously and continuously with hydrogen is of high purity and has high value-added properties. We will continue our research and aim for its commercialization.鈥� The research was sponsored by the Industrial Technology Alchemist Project managed by the Korean Ministry of Trade, Industry, and Energy (MOTIE), Korea Evaluation Institute of Industrial Technology (KEIT) and C1 Gas Refinery R&D Center managed by the Korean Ministry of Science and ICT and the National Research Foundation of Korea (NRF).This is a concept diagram of the production of hydrogen and carbon using direct methane decomposition based on molten liquid alloy catalysts: when methane is injected into the reactor, which is mixed with liquid metal alloy catalyst and zirconia, and heated, high purity hydrogen forms inside the liquid catalyst, while at the same time creating carbon fiber. Carbon fiber is of low density and will float to the surface. This is why it is not affected by the catalytic reaction and long hours of continuous production of hydrogen and carbon are possible.*PhotoFrom far left: Prof. Seo Hyung-tak, PhD students Lee Young-jae and Park Jin-a, and Prof. Kim Yu-kwon

Professor Kim Jong-hyun (Department of Applied Chemistry and Biological Engineering/ Graduate School of Molecular Science and Technology) announced that his team will participate in the Korea-Australia Strategic International Joint Research Project together with Professor Jan Seidel鈥檚 team from the University of New South Wales鈥� (UNSW) Department of Materials Science and Engineering with the aim of developing an IoT-integrated independent sensor module for AI-powered diagnosis of livestock disease. The project period is two years (2021-2023) and will have an expected KRW 1 billion in project expenses.The MSIT has been leading the Strategic International Joint Research Project with an aim to address technological gaps and secure advanced technology through strategic international cooperation, with a view towards the impact of the Fourth Industrial Revolution and the technological abilities of research counterparts with the common goals of addressing climate change, micro dust, infectious disease, and other global challenges. The joint research team plans to develop an independently-run IoT sensor module that monitors the health of livestock in real time to diagnose and forecast pathogenesis, and create data mining analysis-friendly solutions for livestock diseases.A sensor module, which is the development goal of this project, will be designed around an independent power system which does not require replacing batteries and enables detection of various conditions of livestock health at the same time. Accordingly, it is expected to significantly reduce livestock management costs for Australian cattle ranchers as the country has a very large number of grazing livestock. The two countries鈥� research teams plan to lead studies focusing on their specialized fields. Professor Kim Jong-hyun鈥檚 team will develop an IoT-integrated independently-operated sensor module, while the Australian team will optimize a sensor module for localization and analysis of livestock health data. Narromine, a town in Australia, will provide the town鈥檚 livestock data as a test bed for the project so that the sensor module, the outcome of the project, can be adopted by the local agro-livestock industry. Professor Kim, who is heading the project, stated 鈥淥ur team has secured advanced technology through continuous research collaboration with the Australian team,鈥� and added, 鈥淏ased on such collaboration, the bilateral project will enable us to successfully develop an IoT sensor module for diagnosis of livestock disease.鈥� In addition, Kim said, 鈥淎ustralia is home to the world鈥檚 largest livestock headcount in a variety of species combinations, and is therefore very interested in the project. [鈥 Our team has completed the first verification test of a neckband-type sensor module that we developed early on, and is currently discussing management authority of the final product with an Australian company.鈥滱side from joint technological development, which is the primary goal of the joint research project, Kim鈥檚 team plans to strengthen international cooperation and professional training by promoting active exchange of students and researchers between 麻豆影音 and UNSW.In addition to 麻豆影音 and UNSW, other involved institutions include the Korea Institute of Materials Science, the Korea Electronics Technology Institute, Pusan National University, Charles Stuart University of Australia, and the town of Narromine.鞚戈车歆�電� 旮半皹 臧�於曥氤� 歆勲嫧 IoT 韱淀暕順� 霃呺甑彊 靹检劀氇搱 臧滊皽Developing an IoT-Integrated Independently-Operated Sensor Module for AI-Powered Diagnosis of Livestock Disease旮办〈旮办垹Existing Technology甑愳泊順� 氚绊劙毽� 旮半皹鞚� 靹检劀Sensors based on battery swap system靷瀸鞐� 鞚橅暅 臧�於曥氤� 歆勲嫧Diagnosis of livestock disease done by humans鞛愳湪鞝勳洂 氚� 歆勲嫧Autonomous power system and diagnosis鞝滌晥旮办垹(彀硠靹�)Proposed Technology (Differentiation)氚绊劙毽� 鞛愳湪鞝勳洂 IoT 霐旊皵鞚挫姢 靹检劀 氇搱Autonomous battery-powered IoT device sensor module鞁る偞鞕� 順勳灔 鞝侅毄臧�電pplication possible inside or out鞛愳湪鞝勳洂 氇搱Autonomous power module臧�於曥雼� 雿办澊韯� 甑稌Construction of livestock diagnosis data氅�韹� 牍呺嵃鞚错劙 甑稌 臧�電ossible to construct multi-sourcebig data 鞝勳毄, 歆勲嫧Dedicated, diagnostic

Professors Kim Wook and Yang Si-young鈥檚 team confirmed the osteoarthritis treatment mechanism of globular-shaped self-assembled hyaluronic acid nanoparticles. The recent finding is expected to contribute to improving in vivo safety and efficacy of linear hyaluronic acids used in chondroprotective agents for osteoarthritis. Professor Kim Wook (Department of Applied Chemistry & Biological Engineering, left in photo) and professor Yang Si-young (School of Medicine, right in photo) of 麻豆影音 announced that the team has confirmed the chondroprotective efficacy of globular-shaped self-assembled hyaluronic acid nanoparticles and inflammation relief action. This means that target-specific drug carriers can become a potential therapeutic agent for osteoarthritis treatment.The study has been published in Biomaterials (IF 10.317), an international journal exploring the science of biomaterials and their translation towards clinical use, on June 19th with the title, 鈥淪elf-Assembled Hyaluronic Acid Nanoparticles for Osteoarthritis Treatment.鈥漈he number of osteoarthritis patients continues to rise globally as lifespans have continued to lengthen, bringing to population aging. However, injection-type high-molecular-weight hyaluronic acids currently used in drugs and chondroprotective agents are not stable within a living body. The research team focused on self-assembled hyaluronic acid nanoparticles which are mainly used as in-vivo friendly, non-toxic, target-specific and long-acting drug carriers. As compressed globular-shaped self-assembled hyaluronic acid nanoparticles are relatively safer in vivo than linear hyaluronic acids, the team assumed that they are long-standing and provide increased inflammation relief. Accordingly, the team injected self-assembled hyaluronic acid nanoparticles into the knee joint of mouse models and observed through a multiphoton confocal microscope that the nanoparticles that penetrated the cartilage cell membrane conjugated with CD44 receptors and protected joint cartilage against osteoarthritis progression.This is evidence that multiple CD44-binding sites of nanoparticles conjugate with multiple CD44s at the same time, creating CD44 clustering in the cell membrane which effectively inhibits CD44 expression. The research team further explained that the drug carrier鈥攕elf-assembled hyaluronic acid nanoparticles鈥攊tself, without any drug load inside, can inhibit CD44 receptors which aggravate joint cartilage erosion.In addition, the team reaffirmed that CD44 receptors can be a target for developing osteoarthritis treatments. CD44-deficient mouse models showed significantly lower osteoarthritis development compared to the control group with CD44 expression even when artificially inducing osteoarthritis in knee joints. The latest study suggests potential use of self-assembled hyaluronic acid nanoparticles as osteoarthritis treatments that interact with CD44. This recent finding is very meaningful as it provides a clue to overcoming the limitations of current linear hyaluronic acids and their low stability and inflammation-inducing effects due to product degradations.The study was sponsored by the Ministry of Science and ICT and the National Research Foundation of Korea as part of their Middle-grade Research Program and Bio/Medical Technology Development Program.<Self-Assembled Hyaluronic Acid Nanoparticles for Osteoarthritis Treatment Mechanism>
