    Synthesis and On-Field Testing of Novel Low-Cost Latent Fingerprint Development Powders
    Author(s): Gurpreet Singh Suri* and Mohammad Al-Suwaidi

    Background: A series of novel and low-cost powders were synthesised for the detection and extraction of the latent fingerprints deposited on various porous and non-porous surfaces. The template materials for these novel products range from silica nanoparticles to iron nanoparticles and activated charcoal. Preliminary lab testing indicated high quality fingerprints that were developed on various porous and non-porous surfaces such as glass slides, polymer plastic bags, aluminium foil, cardboard and paper. Results: The silica based nano-fingerprint powders gave extremely fine visual prints as compared to commercial SIRCHIE® powders, with a white pattern of the ridges. Activated charcoal based and iron nanoparticles based powders on the other hand yielded fine black fingerprint patterns similar to the commercial S.. Read More»
