Paper Abstract

Computed angle scan tomography has been implemented for the first time using sample raster scanning in a scanning transmission X-ray microscope. The experimental apparatus, acquisition and data analysis procedures, and first results from fully hydrated river biofilm samples measured from 528-534 eV are reported. The multiple energy images are processed to 3-dimensional quantitative chemical maps of major biological components, such as proteins, polysaccharides and lipids.
