“Simultaneous 3D Detection of Organics with Infrared Spectromicrotomography ”
The holy grail of chemical imaging is to provide spatially and temporally resolved information about heterogeneous samples on relevant scales. Synchrotron-based Fourier Transform infrared imaging1 combines rapid, non-destructive chemical detection with morphology at the micrometer scale, to provide value added results to standard analytical methods. Hyperspectral cubes of (x,y, z, Abs ((lamdba please use symbol font))) are obtained employing spectromicrotomography2, a label free approach, it inherently evaluates a broad array of wide organic materials, with minimal sample preparation and modification. Examples presented here (polymer composites, single cells and colonies of cells) demonstrate the broad applicability of this approach to detect complex chemical information of intact samples.
Biography:
Dr. Carol Hirschmugl received her B.S. in Physics from State University of New York at StonyBrook in 1987 and her Applied Physics Ph.D. from Yale University in 1994. She then received an Alexander von Humboldt grant to do research at Fritz Haber Institut, Berlin, from 1994-1996. In 1996 she was awarded the University of Califoria's Presidential Postdoctoral Fellowship to work at Lawrence Berkeley National Laboratory. Since 1997, Hirschmugl has been at the University of Wisconsin-Milwaukee, where she is a professor in the Physics Department and the Director of the Laboratory for Dynamics and Structure at Surfaces.
