하택집 교수 특별 세미나 “Single Molecule Nanometry “ 일리노이대(University of Illinois at Urbana-Champaign) 물리학과 하택집 교수님이 “Single Molecule Nanometry”라는 주제를 가지고 특별 세미나를 합니다. 일리노이대 물리학과 정교수이며 그리고 “Center for the Physics of Living Cells” 의 공동 디렉터 이기도 한 하 교수님은 생물물리 분야를 이끌어가는 세계적 리 더중의 한 분입니다. 특별세미나에서는 생물물리의 최근 동향 및 단일 분자 Nanometry에 대해 강연을 할 것 입니다. 장소: 물리학과 세미나실(제1과학관 31355호실) 시간: 2010년 5월 26일(수) 오후 4시 Abstract: Precision measurement is a hallmark of physics but the small length scale (~nanometer) of elementary biological processes and the thermal fluctuations surrounding them challenge our ability to visualize the motion of biological molecules. In this talk, I will highlight the recent developments in single molecule nanometry where a position of a single fluorescent molecule can be determined with a single nanometer precision, reaching the limited imposed by the shot noise, and the relative motion between two molecules can be determined with ~0.3 nm precision at ~ 1 milliseconds time resolution, and how these new tools are providing fundamental insights on how motor proteins move on cellular highways. Finally, I will show our recent progress in combining angstrom scale optical tweezers with single molecule fluorescent detection, opening new avenues for multi-dimensional single molecule nanometry for biological physics.
