Abstract

We have surveyed the current methods for detection of blood prints and have compared representative procedures from the standpoint of the general type of involved chemistry. We find that the methods that involve fluorescent products produce the greatest sensitivity in concert with laser fluorescence excitation. The ninhydrin/ZnCl₂ procedure is very effective for porous items, including cloth. Merbromin or dichlorofluorescein are effective for non-porous surfaces. Development of blood prints on surfaces that display overwhelming background fluorescence is best performed by peroxidase-type absorption methods.
