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..
When we pour a carbonated drink into a cup, we see small droplets popping over the surface. This happens because air bubbles float up in water and burst on the water surface, ejecting water particles into the air. These water particles are called ‘aerosols.’ In general, aerosols are tiny particles whose size ranges from a few nanometers to several micrometers that freely float in the atmosphere. Water droplets, dust, smoke, and water haze are typical examples of aerosols. They may either act as cloud condensation nuclei stimulating cloud formation, or scatter and absorb solar light..
It is not uncommon for diseases such as diabetes, hypertension and cancer to develop complications. Recently, a research team led by Professor Sanguk Kim of Department of Life Science successfully devised a method for predicting disease complications based on comorbid disease pairs by employing a network medicine approach. Jointly with Professor Sung Ki Jang of Life Science, PhD candidate Solip Park, and Professor Juyong Park of Kyung Hee University, Professor Kim published a paper, ‘Protein localization as a principal feature of the etiology and comorbidity of genetic diseases’ in..
Atransparent and flexible organic transistor was recently developed by a POSTECH-SKKU joint research team. Professors Kilwon Cho and Kwang Soo Kim teamed up with Professor Byung Hee Hong at Sungkyunkwan University and worked on graphene, the ‘dream material,’ stepping into the market of next generation displays such as transparent monitors, windows, and flexible displays that can function like GPS navigation systems on automobiles and wearable electronic devices. The research team used graphene as electrodes for Organic Thin-Film Transistors (OTFTs) and successfully produced a flex..
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..
Water probably is the greatest enemy for most electrical devices; water short-circuits electric devices. Therefore the demand is high for developing water-resistant components, and in particular, those to be used for expensive, high-performance electronic devices. Professor Kijung Yong of Department of Chemical Engineering and PhD candidate Seunghyup Lee have utilized the ‘lotus leaf effect’ with nano materials and manufactured an electronic device that shows stable performance even when soaked in water. The result was published online in Advanced Materials, a renowned journal in m..
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..
Professor Kwang Soo Kim has come forth with a revolutionary and unprecedented method for DNA sequencing that can potentially decode 3 billion pairs of human genes in an hour. The field of DNA sequencing caught the world’s attention when the Human Genome Project was successfully completed in 2003, and many developed nations have since been competing to develop ways to increase the speed of genetic sequencing and analysis. This research is closely related with treating intractable or rare diseases and therefore will have important implications for life science. Professor Kim, well-known fo..
In 2008, POSTECH Alumnus Dr. Donghun Lee made an unexpected discovery during his study of single dopants in Gallium Arsenide (GaAs) semiconductors, which are used for satellites or military products. A dopant is a substance that produces a desired electrical characteristic for semiconductors, and Dr. Lee had been studying a defect semiconductor where one of the lattice points had a dopant atom missing. He experimented by pushing the atom to the next lattice point, and surprisingly, the atoms automatically rearranged themselves to fill the vacant places as in a puzzle game. Now the defect produ..
As it is better to wear clothes that fit you well rather than to try on many possible sizes, it is also most prudent to take pills that cure your ailments precisely without triggering unwanted side-effects. A POSTECH joint research team has contributed to the forthcoming era of customized medicines by developing a very precise way to detect the genetic variations among individuals. The team has made it possible to prescribe appropriate therapeutic administrations for each individual. This new technology can assign the most appropriate pills for a cold, anticipate the effects of new anti-cancer..
