The role and impact of Aluminium oxide nanoparticles in crime investigation

Abstract

Nanotechnology is an important and powerful tool in most the areas including medicine, imaging, and forensic sciences. It is rapidly growing region of research with potential in various fields, running from medical care to production and physical science. Nanotechnology has a potential to make significant positive contribution in forensic science in crime detection. Forensic science applies knowledge and methods from natural science in order to identify, individualize, and assess evidence. Hence, with the aid of evidence, crime scenes can be rebuilt, investigations can be directed, and offenders can be prose cuted. Nano-analysis use tools like UV Vis spectroscopy, atomic force microscope (AFM), XRD, EDX, Raman micro spectroscopy (Raman), scanning electron microscope (SEM), and transmission electron microscope (TEM) (Raman). Moreover, in current article, an attempt was made to elucidate how nanotechnologies could be crucial in addressing current forensic investigation issues such as explosive detection, forensic toxicological analysis, finger print analysis, forensic DNA analysis, detection of explosive residue, forensic nano trackers, drug facilitated crime.
