POSTECH Department of Chemical Engineering Professor Hyung Joon Cha and his team’s research on bone graft material binder technology was published in the Journal of Materials Chemistry B.Mussels stick to rocks because its protein has strong adhesive properties. This protein has been used as a binder for bodily wounds and surgery. An engineered mussel glue protein,a promising functional binder for the acceleration of bone substitute-assisted bone regeneration,has been developed by the joint research team of POSTECH and Korea University Anam Hospital, which can be used in teeth implants. ..
A research team, led by Department of Materials Science and Engineering Associate Professor Sei Kwang Hahn and graduate student Hwiwon Lee, has published research on a new rheumatoid arthritis treatment. The article “Hyaluronate – Gold Nanoparticle/Tocilizumab Complex for the Treatment of Rheumatoid Arthritis” was published in the April 2014 edition of the ACS Nano, a monthly scientific journal published by the American Chemical Society. Rheumatoid arthritis (RA) is a chronic inflammatory immune disease that affects 0.5 to 1 percent of the adult population worldwide and ..
Professor Dong-Woo Cho’s team at POSTECH is engaged in the development of novel tissue and organ printing technology that can bridge that gap that currently exists between the supply and demand of tissues and organs for patients suffering from tissue loss or organ failure. This novel tissue printing technology could lead to the regeneration of healthy functional tissues or organs for patients, thus, eliminating the need for tissue grafts and mechanical devices. The POSETCH team made up of Falguni Pati, Jinah Jang, and Dong-Heon Ha, recently published their findings in an article entitle..
Professor Suk Bong Hong(CE and School of Environmental Science and Engineering) and Hyung Ki Min(CE, Ph.D. candidate) succeeded in converting meta-xylene to para-xylene using zeolite catalyst based on gas chromatography-mass spectrometry-computer(GC-MS-CPU) and isotope exchange method. Para-xylene which is used to make polyester fibers, plastic bottles, and films is a basic petrochemical material made through isomerization of meta-xylene, whose mechanism has been merely a hypothesis. Unlike other technologies, this technology can now be realized ex hypothesi.The research team is receiving atte..
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..
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..
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..
Professor Kwan Hyoung Kang of the Department of Mechanical Engineering developed anelectrohydrodynamic (EHD) pumping method for dielectric (or non-polar) liquids utilized for micro fingers of microsurgical robots. He presented a new way which relies on the EHD flow generated by the filed dependent electrical conductivity.The EHD pump is a device that converts electrical energy to mechanical energy indirectly, and it is required for the cooling system of microelectronic devices for chemical and biological analysis and micropumping of organic solvents.The results of this research are significant..
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..
