ABSTRACT
The fingerprints left by the perpetrators are the first thing a forensic
team searches for during a crime investigation. These prints could be
visible or hidden (also known as latent). The development of these
latent fingerprints on various surfaces is done using a variety of
approaches. An important and useful method, most commonly used
in forensic investigations for wet surfaces involves Small Particle
Reagent method. In present work, we report the use of a UV
fluorescent Schiff's base as an effective organic compound which has
been employed as a small particle reagent. It has been used for the
visualisation of latent finger prints on various non-absorbent surfaces.
The advantage of employing this Schiff's base as a small particle
reagent over previously utilised dyes is that it is less expensive,
contains no heavy metal, and may be used on a variety of surfaces.
Furthermore, while taking images, visualisation does not necessitate
the use of a particular UV lamp or filter.
