Forensic chemistry is the employment of analytical methods and techniques to analyse and investigate evidence in forensic science. In the past years an unofficial subsection of forensic chemistry, termed as “Forensic Electrochemistry” has become a prominent topic in scientific literature, reflecting the rapid growth of forensic analysis. Electrochemistry, in favour of its intrinsic characteristics, has been considered an advantageous tool in this expanding field. The aim of this chapter is to outline key principles, landmarks and recent developments of forensic electrochemistry, focusing on fingerprints, gunshot residues, explosives, illicit and date-rape drugs.
