Unlocking Mysteries: The Cutting-Edge Fusion of Nanotechnology and Forensic Science

The convergence of nanotechnology and forensic science presents a transformative era for criminal investigations. This review article explores how a diverse range of nanomaterials, including carbon-based nanomaterials (like graphene oxide and fluorescent carbon dots), metallic nanoparticles, and polymeric nanofibers, are revolutionizing various forensic disciplines. From the superior performance and non-toxic nature of graphene oxide in latent fingerprint detection to the rapid cocaine analysis enabled by 3D-printed electrodes, nanotechnology is pushing the boundaries of forensic capabilities. Its applications extend beyond these examples, with nanocomposites comprised of various nanomaterials offering practical solutions for heavy metal extraction in environmental forensics. Trace evidence analysis is experiencing a boost through the use of different nanomaterials, including fluorescent carbon dots, enabling enhanced visualization and targeted detection. Furthermore, high-throughput nanotechnology platforms are addressing limitations in DNA sequencing, paving the way for faster and more cost-effective genetic analysis. Even document examination stands to benefit from non-destructive nanoscale sensors, preserving the integrity of evidence. However, integrating nanotechnology into forensic science necessitates navigating regulatory and environmental hurdles, while upholding ethical and procedural standards. This review delves into these advancements, highlighting the anticipated trajectory of nanotechnology in forensics and the ethical considerations that must be addressed for its successful implementation.
