Abstract
Conversion of osmified tracheal cartilage constituents into an array of laminar interference gratings has been attained by three tandem reactions. Oxidation of semithin, LR white-embedded cartilage sections by acetic anhydride in dimethyl sulfoxide is the first step in the conversion process. Subsequent addition reactions of oxidized cartilage pyranoses and furanoses with thiocarbohydrazide constitutes the second step. Reduction of silver proteinate by thiocarbohydrazones and the concomitant coating of cartilage constituents with silver gratings completes the conversion of cartilage sections into a system of layered interference filters. In transmitted light, all components of converted cartilage display vivid structural colors, which allow detailed microscopic analysis of structurally colored cellular and extracellular cartilage constituents.
