Abstract

This chapter covers the range of electrochemical approaches for a variety of chemical sensing utilised within forensic analysis. Electrochemical based sensors are powerful analytical tools which can be exploited by the forensic community and they have found widespread applications within the fields of illicit drug detection, toxicological analysis, alcohol detection and explosives analysis. This chapter presents an overview of these applications of electrochemical sensing and an assessment of current technological advancements as well as future areas of research. Within the forensic community the need for versatile, portable, selective, sensitive and robust methodologies has made electrochemical sensors an attractive alternative to more traditional analytical technologies. Herein, we will highlight the distinctive prospects electrochemistry offers to the field of forensic chemical analysis as well as showcasing the most significant advancements to date.
