It is evident that the application of nanoscience in a forensic investigation has helped criminologists to solve crime mysteries in less time and with greater efficiency. The rapid advancements in forensic science come with technological improvements in nanotechnology. This article highlights some of the major achievements in forensic science based on nanotechnology.
Identification of Fingerprints
Fingerprints have been used as unique evidence by criminologists since ancient times. Latent fingerprints are developed from several colored materials such as aluminum 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.
