TITLE: New Methods of Using "Density" in Analysis
SPEAKER: George M Whitesides
ABSTRACT OVERVIEW: This seminar will describe two new methods of using densities to carry out separations and analyses. One is based on magnetic levitation of diamagnetic objects in a paramagnetic medium in a magnetic field gradient; the second on differences in density in solutions of polymers. It will cover both a description of the science that underlies these methods, and examples of applications.
