Fingerprints have been utilized in criminal and judicial investigations for establishing the identity of the accused/suspects for a long time. Fingerprints are an effective
tool for determining who committed a crime. Nonetheless, easily detectable or visible
marks are infrequently found at a crime scene; most of the time, they are latent, requiring the use of special methods to identify them. Fingerprint comparison should be cost
effective and time bound to quickly obtain results with quality assurance. In this case,
nanotechnology and its continued development have resulted in a range of applications in forensic science. Nano particles have been proposed as a solution for fngerprint
detection and enhancement due to their versatility and smaller particle size. Because
nanoparticles do not alter the composition of evidence, they can easily aid in the detection of high-resolution prints, and these evidences, unlike conventional techniques, can
be re-used for any other chemical treatment. In most legal science research facilities,
traditional methods such as black powder, fluorescent powder, and white powders are
used. Tis review paper summarizes the various types of nanoparticle techniques that
can be used for fngerprint identifcation and comparison, such as Camphoric-based
Nano carbon, Acetylated cashew gum based silver nanoparticles and so on.
