Colorized scanning electron micrograph of partially dried red blood cells clotted on the cotton fibres of a gauze wound dressing. Image was collected at low vacuum to avoid charging of cotton fibres

Human duodenal epithelium, at the level of the crypt. Fixation was performed in buffered formal-calcium. Peroxisomes are stained with DAB by their catalase activity at pH 10.5, postosmicated and embed...
