Organic-Base Fluorescent Powders for Latent Fingerprint Detection on Smooth Surfaces: Part II

Abstract

A new class of organic base fluorescent powders can be used for developing fingerprints on nonporous surfaces (e.g., plastics, poly bags, glass, metals, etc.), multicoloured and coloured glossy surfaces. These powders are also extremely good for enhancing weak prints, developed with other commercially available powders or with cyanoacrylate esters, the prints developed with fluorescent powders show extremely high fluorescence under long wavelength UV light.
