A new method for locating saliva stains-spotty paper for spotting spit

G M Willott et al. Forensic Sci Int. 1980 Jan-Feb.

Abstract

A convenient method of locating saliva stains has been devised. Filter paper covered with blue coloured starch fragments is laid on the material to be tested. Salivary amylase hydrolyses the starch on the areas of paper corresponding to saliva stains, which are then delineated as clear zones whereas negative areas remain speckled with blue particles.
