[Illinois] Beckman Graduate Seminar: Dispersion-relation Spectroscopy of Intracellular Transport
18 Dec 2012 | | Contributor(s):: Ru Wang
The interior of a living cell is a busy place. Molecular motors move materials along prescribed biopolymer tracks. This sort of active transport is required to rapidly move products over large distances within the cell, where passive diffusion is too slow. Just as understanding the flow of...

[Illinois] Beckman Director's Seminar - Quantitative Phase Imaging
26 Nov 2012 | | Contributor(s):: Gabriel Popescu
"Ever since the invention of the microscope in the 17th century, it has been observed that live cells are transparent under visible illumination, i.e. they do not absorb (or scatter) light significantly. Thus, a magnified image of cells will generally exhibit low contrast. In order to overcome...
