[기계전공세미나-열공학,정밀기계설계특강2] Bacterial Actuation, Sensing and Transport at Micro/Nanoscales
1. 제 목 : Bacterial Actuation, Sensing and Transport at Micro/Nanoscales
2. 연 사 : Professor MinJun Kim (Drexel University Department of Mechanical
Engineering & Mechanics School of Biomedical Engineering)
3. 일 시 : 2008년 9월 19일(금) 16:30-17:30
4. 장 소 : 301동 105호
5. 내 용 :
Although nano/microfabrication techniques are rapidly advancing it remains a challenge to fabricate separate individual nanoscale structures and actuators en masse. A possible resource for fabricating such tiny elements exists within microorganisms. Specifically, bacteria produce an assortment of objects from polymeric biomolecules. This talk will discuss the practical integration of biomolecular motors for biologically powered microfluidic systems as well as the development of polymeric protein nanostructures such as bacterial flagellar filaments for use in micro and nanoscale devices. Bacterial flagellar propulsion represents an extraordinary system in nature for generating motion at the small scale. Due to their unique molecular polymeric structure can adopt different shapes, depending on the local chemical and flow conditions. Their motion induces a local flow that can be used to propel cells, as well as much larger structures through a fluid environment. The control of microbots powered by bacterial teamsters will be highlighted through the talk. The use of biological nanostructures in engineered systems represents a critical step toward understanding both how the biological world has evolved at the nanoscale as well as how scientists and engineers can mimic and improve on nature using modern fabrication and assembly. In addition to the bacterial actuation and transport at micro/nanoscales, the possibility of using nanopore technology and synthesis of gold nanorods will be introduced to detect and configure bacteria/viruses in water for the identification of certain types of pathogens.

Dr. MinJun Kim is an assistant professor in Department of Mechanical Engineering & Mechanics and School of Biomedical Engineering, Science and Health Systems at Drexel University. Dr. Kim completed his M.S. and Ph.D degree at Texas A&M University and Brown University, respectively. He received his B.S. degree in Mechanical Engineering from Yonsei University in Korea. During his doctoral studies at Brown, he held the prestigious Simon Ostrach Fellowship and also spent one year working as a postdoctoral research fellow at the Rowland Institute at Harvard in Harvard University. His research interests span the topics of biological actuation, sensing, and transports (BAST), nanopore sensors for single molecule analysis, and optical diagnostics for bio/micro/nanofluidics. For the past several years, Dr. Kim has been experimentally investigating biological transport phenomena in synthetic nano/microscale architectures to produce new types of bionanotechnology. He is a recipient of National Science Foundation CAREER Award and Louis & Bessie Stein Fellowship.
