Role of Nanoparticles in Latent Fingerprinting: An Update

Abstract

Nanotechnology is an escalating branch whose feelers are mesmerizing nearly every field of science. It is the evolving field in forensic science, the advancement of emergent techniques of nanoparticles being unified with latent fingerprinting. The size of nanomaterials made them unique and have adjustable mechanical, electrical, and optical properties. At the crime scene, the prints that are left behind are generally latent (invisible) fingerprints. The Current review paper encompasses the synthesis of nanoparticles from conventional and advances synthetic pathways. Their applications, with and without modifications and their impacts on the enhancement of latent fingerprints, have also been discussed.
