When looking down on streets of Chicago from the 30th floor of a skyscraper, one would see a high density of cars and people buzzing around all over the place. It would appear as if everyone was everywhere at any given time. When observed at an individual level, however, one would exhibit a...

Illinois iOptics Lecture 3: A tissue scattering-phase theorem
17 May 2010 | Online Presentations | Contributor(s): Gabriel Popescu
We have derived two mathematical relationships between quantitative phase images of thin tissue slices and the scattering parameters of the bulk, i.e. scattering mean free path, ls, and anisotropy factor, g. The ls turns out to be inversely proportional to the mean-squared phase shift and g is...
Illinois iOptics Lecture 5: Deposited Nanorod Films for Biosensor Applications
17 May 2010 | Online Presentations | Contributor(s): Brian Cunningham
Planar photonic crystals have been used as the basis of many biological sensing devices. Here, we successfully demonstrated that the combination of a photonic crystal structure and a dielectric nanorod coating prepared by the glancing angle deposition technique can lead to significant increases...

Illinois iOptics Lecture 1: Super Accuracy and Super-Resolution of Molecular Motors and Ion Channels
16 Apr 2010 | Online Presentations | Contributor(s): Paul R Selvin
The standard diffraction limit of light is about 250 nm, meaning that you cannot "resolve" objects closer than this distance. Despite this, we have come up with a method to measure individual biomolecules with 1.5 nm spatial localization in x-y plane and 1-500 msec temporal resolution, using a...
