Nanotechnology and Its Uses in Forensic Science

Nanotechnology has had a significant impact on the field of forensic science. Different nanoparticles, including silver, zinc oxide, silicon dioxide, aluminum oxide, gold (with the silver physical developer), europium, fluorescent carbon, and amphiphilic silica, could be applied to a variety of object surfaces to produce characteristics like distinct ridge details of fingerprints; among all of these, gold is the most frequently used. The fingerprint is regarded as significant evidence at any crime scene, and nanotechnology has enormous potential for fingerprint analysis in the future. This chapter will explore the current and potential applications of nanotechnology in forensics. The chapter will begin by introducing nanotechnology and its potential applications. A discussion of the advantages and limitations of nanotechnology in forensics will follow this. The chapter will then explore the current and emerging nanotechnology techniques used in forensic science. These techniques include nanoscale imaging, nanoscale spectroscopy, nanoscale chemical analysis, and nanoscale DNA sequencing. Finally, the chapter will discuss the implications of nanotechnology for the future of forensics.
