Development and Comparison of Normal and Sun exposed Latent Fingerprint using Nanoparticles on Porous, Semi-porous and Non-porous Surfaces

Author(s) Mr. Brinesh Pradhan
Country India
Abstract This study investigates the use of nanoparticles to enhance latent fingerprints on porous, semi-porous, and non-porous surfaces under both normal and sunlight-exposed conditions. Findings show that nanoparticles can effectively develop fingerprints on all surface types, though performance varies—non-porous and semi-porous surfaces yield clearer results than porous ones. Sunlight generally reduces print quality, but certain nanoparticle formulations still enhance visibility. The research highlights nanoparticles' potential in forensic fingerprint analysis and suggests further work to improve their efficiency and application methods in the field.
