Abstract

This chapter discusses the great potential of functional graphene-based nanosensors in forensic investigation. There are several limitations faced by forensic investigators in analyzing trace amounts of illicit drugs, narcotics, toxins, and explosives because of the sensitivity, specificity, selectivity, chemical and volatile nature of explosives, and impurities in the residues collected from the crime scene. This chapter highlights the application of functional graphene-based nanosensors and graphene quantum dots in improving forensic analysis by enhancing the sensitivity of these carbon-based nanoparticles and optimizing the response range of sensors. The major focus of this chapter will be on the application of graphene nanosensors for the detection of trace amounts of illicit drugs, narcotics, and explosives that are collected from crime scenes. It will also entail a comparison of the application of graphene nanoparticles and metallic nanoparticles for drug analysis.
