Summary 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 μm was attained. The fossil diatom image shows a clear difference below and above the carbon K‐absorption edge (4·46nm).
