Quantitative Mapping of the Orientation of Fibroin β-Sheets in B. m ori Cocoon Fibers by Scanning Transmission X-ray Microscopy
Abstract
The spatial distribution of the linear dichroic signal associated with aligned beta-sheets in a microtomed section of a Bombyx mori cocoon silk fiber was derived from scanning transmission X-ray microscopy (STXM). The intense C 1s --> pi(amide) peak at 288.25 eV was found to have negligible dichroic signal in transverse sections but a large dichroic signal in longitudinal sections. This is consistent with other measurements of the orientation …
