Forensic Nanotechnology

Recently, Nanomaterials have found application in the field of Forensic science with appropriate functionalization techniques. It is possible to develop significantly less-toxic Nanomaterials that have a greater advantage over conventionally used dyes and chemicals for the detection of trace evidence and detection of latent fingerprints, DNA, illicit drugs, fraudulent notes or currencies, chemical and biological warfare agents.  Fingerprints are developed from several colored materials such as aluminium flake on a dark background and carbon soot on a light background. However, these materials have major drawbacks such as unclear images of the fingerprint. This problem is solved by using Nanotechnology-based materials.
