Use of a Fluorescent Schiff’S Base as Developing Agent for Latent Finger Prints

During investigations of a crime, the first thing that a forensic team looks for is the finger prints left by the culprits. These finger prints may be visible or latent. Various methods are used for the development of these latent fingerprints on different surfaces. Amongst these methods, powder method is still the most preferred one in forensic investigations due to its simplicity and efficiency. In this paper we report the application of a UV fluorescent schiff's base as an efficient organic compound in various powder formulations for the visualization of latent finger prints on different absorbent and non absorbent surfaces. The results obtained showed clear ridge details in almost all the cases. The benefit of using this schiff's base in powder formulations over the earlier used powders lies in the fact that it is economical, does not contain any heavy metal and can be used on objects of various colours. Further the visualisation does not require any specific UV lamp or filter to take the photographs.
