Professor Sangmin Jeon (CE) and Jinmyoung Joo (Post Doc.) have developed the technology that diagnoses cancer by using micro-oscillators made of photo- catalytic silicon and nanoparticle on the inside and magnetic material on the outside. This technology, published on ACS Nano, attracted academic attention because it could be applied to cancer diagnosis at once as well as early detection, which is crucial in cancer treatment.When patients suffer from cancer, the concentration of specialized proteins in blood and other body fluids increases. This technology uses the concentration of the protein..

Professor Kijung Yong (CE) and his research team succeeded in developing a nonvolatile memory cell which is waterproof and maintains information without power supply. Nonvolatile memory cells could be used in production of waterproof computers and smart phones by using nanotechnology.Memory cells currently used are vulnerable to water. To solve this problem, the research team synthesized the tungsten oxide semiconductor using natural effects called the Lotus Effect, an imitation of lotus leaves, which could wash the dust off the surface without wetting it. In addition, they developed resistive..

Baekhee Lee (IME Ph.D. candidate) and Jihyoung Lee (IME M.S. candidate) of the Ergonomic Design Technology Lab (advisor Professor Heecheon You) invented the “PC based glaucoma detector,” which can be easily installed on a PC to test one’s sight and development of glaucoma.The detachable, newly developed equipment effectively induces eye movements and allows for a self-vision test. The result is further used to analyze the progress of optic nerve damage, therefore the diagnosis of glaucoma.Glaucoma is an eye disorder in which the optic nerve is damaged, permanently impairing v..

A new leaf-mustard kimchi season is here, stimulating appetites with the unique flavor and aroma of leaf mustard and ground red chili, plus the promise of enriched calcium.The joint research by Professor Youngsook Lee of the Department of Life Science. and Dr. Won-Yong Song and Prof. Martinoia of University of Zurich have created a way for producing the calcium-rich product.The research team found that the protein, BjPCR1, facilitates transportation to calcium absorbed from root hair of plants to inner cells. Prof. Lee’s research team demon-strated the fact that BjPCR controls the transp..

The research team of Professor Hyung Joon Cha (CE), Prof. Dong-Woo Cho (ME), and Prof. Rhie, Jong Won (The Catholic University of Korea) succeeded in developing functional three-dimensional scaffolds that enhance regeneration of bone tissue. Using mussel adhesive proteins, it is safe for the human body. It is also proven to be remarkable in adhesion and coating. This research was published in the Apr. 2 online version of Acta Biomaterialia, a renowned academic journal in the field of body materials.The research team affixed the stem cell on the surface of the polymer using the mussel-extracted..

Professor HyungJoon Cha of the Department of Chemical Engineering has devised a new technique which combines Mussel Adhesive Protein (MAP) and antibody-binding protein to pin down an antibody on diverse surfaces coated with a new linker protein (BC-MAP).BC-MAP is a linker material to immobilize y-shaped antibodies onto immunosensors such as a pregnancy test which examines for infection by antigen-antibody reaction. In order to work properly, antibodies are supposed to be exactly immobilized onto surfaces.Previously, antibody-binding protein did not immobilize an antibody depending on the surfa..

Professor Hyun M. Jang of the Department of Material Science and Engineering and a research team led by Jung-Hoon Lee, advised by Prof. Jang, recently discovered that Samarium ferrite (SmFeO3) is a multiferroics exhibiting connection between the order parameters. The result from Prof. Jang’s experiment was posted on Physical Review Letters, an authoritative paper in the physics area.Since SmFeO3 consists of orthorhombic structure, it has been known as material without magnetization; however, Prof. Jang and his research team found it actually has electrical polarization without any electr..

POSETCH researchers have successfully developed the particle beam technique to eliminate nanometer-sized contaminant particles (CPs) of nano-scale devices, for the first time in the world.A research team led by Professor Jin Won Lee of the Department of Mechanical Engineering has succeeded in developing the technology to completely remove 10 nm-sized CPs using a revolutionary beam technique that uses nanometer-sized bullet particles (BPs) moving at supersonic speed. The research result has been published in the online edition of Nanoscale Research Letters on Apr. 11.Due to the attraction by su..

Solar cells are converters that make electricity out of light energy by the photovoltaic effect. Made with organic semiconductors, organic solar cells are light and flexible, can produce electricity with a small amount of sunlight, and can be manufactured at a low cost. As a result, they are suitable for products that need self-generated electricity such as solar windows or certain military products rather than for solar power plants. In Angewandte Chemie, a renowned journal for the field of chemistry, a POSTECH master’s student published a paper on a new manufacturing technology for org..

Asmart nanomedicine customized for liver diseases has been developed by Professor Sei Kwang Hahn’s research team in the Department of Materials Science and Engineering. Hyaluronic acid is a bio-polymer of high biocompatibility and stability, and can be target-specifically delivered to liver tissues. Capitalizing on this characteristic of hyaluronic acid, Prof. Hahn built a liver-targeted drug delivery system, which is expected not only to reduce serious side-effects of the conventional uncustomized medications, but also to advance the effectiveness of the drug for hepatitis, liver cirrho..
