Abstract
Abstract With the development of science and technology, forensics has become a more attractive scientific subject to study, and the field of nanoforensic research has seen a lot of interest in nanomaterials. Fingerprints are crucial pieces of evidence at each crime scene, and future fingerprint investigations could greatly benefit from nano-based procedures. In terms of tangible evidence for proving a person’s identity, fingerprints have historically been and now are considered to be the most valuable sort. The prints left behind at a crime scene are typically latent (invisible) fingerprints; therefore, the distinctive ridge details of fingerprints can be obtained by coating various object surfaces with various nanoparticles, with gold being the most popular choice. These nanoparticles include silver, zinc oxide, silicon dioxide, aluminum oxide, gold, carbon, and silica. Latent fingerprints can be made better and more stable using nanoparticles. This review study concentrates on the employment of various nanomaterials in the creation and identification of latent fingerprints as a consequence.
