Dr. Susanne Ullrich will host Dr. Peter Kner of the Department of Engineering at the University of Georgia this week. His talk is entitled "Increasing Resolution in Biological Light Microscopy."

Light Microscopy is an essential tool in biology research because it allows biologists to study cell structure and the behavior of individual proteins within the cell. Unfortunately the resolution of classical light microscopes is limited to roughly 200nm, much greater than the size of many biological structures. Recently there has been a lot of progress in developing techniques to improve the resolution of fluorescence microscopy beyond 200nm. In this talk, I will give a brief overview of the history of light microscopy and discuss recent advances in overcoming the 200nm resolution limit.
