Forensic nanotechnology is the use of tiny tools and materials—called nanotechnology—to help solve crimes. These tools are so small that they can detect things that normal methods might miss.For example, scientists can use nanotechnology to find very small traces of blood, fingerprints, or drugs at a crime scene. It can also help identify people through DNA or detect dangerous substances like explosives or toxins.Because nanotechnology is so precise, it makes crime investigations faster, more accurate, and more reliable.At events like the NanoTechnology World Conference, experts talk about the latest advances in forensic nanotechnology and how it is helping police and investigators solve crimes more effectively.
