Nano Forensic Testing of Illicit Drugs

Abstract

Nano forensics utilizes nano-based sensors in matters of crime or where the legality of the process is challenged. There exist many conventional techniques, but considering the approach of criminals and the modern-day standard of investigation, there is a need for nanotechnology-based sensors for their sensitive, selective, and rapid detection of illicit drugs. Illicit drugs are psychoactive in nature. They act upon the CNS that results in different perceptions and long-lasting responses. This chapter covers the drugs that can be the potential source of causing abuse and those commonly detected in forensic lab testing. The conventional techniques have a few drawbacks. They are time-consuming, highly expensive, and some of these techniques are also destructive. Nanosensors are nanoparticle-based probing techniques that constitute a sensing platform for the detection of the biological substance present in the evidence sample collected from the crime scene. These nanosensors can work with limited quantities, and the quality of the sample yields valuable information for preparing the scientific report.
