Revolutionizing Forensic Science: The Role of Nanotechnology in CrimeDetection and Analysis

Abstract: Nanotechnology, through its manipulation of materials at the nanoscale, is revolutionizing forensic science by advancing evidence detection, interpretation, and identification. This study explores its application across key areas, including chemical warfare detection, forensic toxicology, fibre and hair analysis, bloodstain analysis, and document examination. Nanotechnology enables the development of highly sensitive nanosensors for detecting trace chemicals, enhances the identification of molecular signatures in fibres and hair, and improves the sensitivity and accuracy of toxicological analyses. In bloodstain analysis, nanoparticles amplify trace detection, while in document examination, nanotech techniques aid in identifying forgeries and alterations. These innovations highlight the transformative impact of nanotechnology on forensic science.
