Abstract
This paper proposes an alternative solution to multimetal deposition (MMD) for the development of latent fingermarks on non-porous and porous surfaces. MMD offers a good sensitivity, however it is very time-consuming and requires many reagents to be carried out. Single-metal deposition (SMD) replaces the silver enhancement of the gold colloids by a gold enhancement procedure. This reduces the number of baths by one as well as the number of reagents and their cost, utilizes reagents with a longer shelf life, and most importantly reduces the labor-intensity of the procedure. It offers quasi-identical results to MMD and thus makes a very attractive alternative.
