Abstract:
Dried biological specimens, such as fossil diatoms, collagen, nerve tissue and spicule of Trepang, were observed by X-ray photoelectron-conversion contact microscopy. A spatial resolution of 0.2 microns was attained. The fossil diatom image shows a clear difference below and above the carbon K-absorption edge (4.46 nm).
