The research team of Professors Jaesung Park (Department of Mechanical Engineering) and Yong Song Gho (Department of Life Sciences) has developed a way to generate artificial nanovesicles that can be used to deliver RNA, a breakthrough that is expected to be used in exosomes research and to have applications in drug and RNA-delivery systems. Their paper, "Microfluidicfabrication of cell-derived nanovesicles as endogenous RNA carriers”,made it onto the cover of the journalLab on a Chipand was selected as a Hot Article. Exosomes/microvesicles are known to shuttle biological signals..
Using POSTECH Professor Chulhong Kim’s custom-built high-resolution photoacoustic imager, researchers were able to examine the combination of nanonaps and photoacoustic tomography illuminated inside the intestine of a mouse. (Credit: Chulhong Kim) Millions of people worldwide who suffer from digestive diseases may soon have a safer alternative to traditional radiological techniques when visiting the hospital for imaging of the gastrointestinal tract. Researchers from the Pohang University of Science and Technology (POSTECH), the University at Buffalo, and University of Wisconsin&ndas..
Professor Sung H. Han (Department of Industrial and Management Engineering) is an authority in the field of ergonomics, an applied science that deals with the design of devices and systems in conjunction with the physical working conditions, capacities, and requirements of the user. Professor Han has conducted research on human-computer interaction,effectiveproduct design, and the evaluation of product and service experience to provide better value to users. He has played a vital role in the establishment of Asia’s first National Institute of Ergonomics and is the founder of ACED (Asian ..
Professor Sei Kwang Hahn and co-workers in the Department of Materials Science and Engineering at POSTECH, and Professor Allan S. Hoffman at the University of Washington, have investigated various kinds of hydrogels developed for stem cell therapy as a regenerative medicine. Their work is published in the latest edition of Progress in Polymer Science (IF = 26.854), an international peer-reviewed scientific journal in the field of polymer science and engineering. The paper entitled “In situ-forming injectable hydrogels for regenerative medicine” describes advanced polymeric hydrogel..
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. ..
Noise plays a key role in important biological processes, such as bacterial antibiotics resistance, cancer development, and stem cell differentiation. Physics can explain much of this biological phenomenon. Professor Nam Ki Lee of the Department of Physics and the School of Interdisciplinary Bioscience and Bioengineering with Department of Physics graduate students Sora Yang, Seunghyeon Kim, Cheolhee Kim, Hyeong Jeon An and Professor Jaeyoung Sung of Chung-Ang University studied how cells propagate noise using RNA polymerase. Their research was published in this month’s Nature Communica..
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..
Professor Nam -Ki Lee (i-Bio and Physics) su- cceeded in find- ing the step-by-step processes of neurotransmitt- ers in the brain cells through the single molecule technique, which had previously been unknown. This principle allows for possibilities to understand the causes of brain cell damage when patients suffer from intractable cerebropathy such as dementia.Prof. Lee’s research team jointed with Prof. Yeon-kyun Shin (KIST) to discover the fact that synaptotagmin-1, which is protein in biological membrane, controlled fusion of cell membrane in process of releasing chemicals by gradati..
The HangulBot, developed by the research team of Professor Sonya S. Kwak (HSS), won the Delegate’s Choice prize on Dec. 8 at the International Conference on Social Robotics 2011 held in the Netherlands.The robot, developed by Prof. Kwak, Song Young-bin (CSE 08), Park Joon-sin (ME 09), Eun Ho Kim (KAIST), and Ji Myung Kim (KAIST), was designed for children and non-Koreans. By rotating and rearranging a consonant block and a vowel block, learners can understand the concept of the phonetic aspect of the Korean language in a short time.The robot was designed to perceive the arrangement of th..
