Spectroelectrochemistry: Drug Identification in Forensic Applications

August 23, 2022
10:00 a.m. PDT, 1:00 p.m. EDT, 18:00 BST, 19:00 CEST
Duration: 60 Minutes


In forensic chemistry, the presence of drugs and novel psychoactive substances at low concentrations or in complicated mixtures present challenges to traditional analytical screening methods. At the same time, ensuring timely investigative information, determining appropriate analytical schemes and improving the safety of laboratory personnel, healthcare practitioners and crime scene investigators is crucial.

In this webinar, Colby Ott, PhD, Research Scientist at West Virginia University and Luis E. Arroyo-Mora, PhD, Professor at the Department of Forensic and Investigative Sciences at West Virginia University, will present the fundamentals behind electrochemical-surface-enhanced Raman spectroscopy (EC-SERS) and how the advantages of this technique can be leveraged for on-site screening of drugs of abuse. Our experts will describe how the SPELEC combination potentiostat-Raman spectrometer serves to provide simple, time-resolved data and how EC-SERS can be applied to other applications. Tune in to learn about two EC-SERS methods and their analytical performance as well as an assessment of authentic casework samples which will demonstrate the strength of this approach.

Key Learning Objectives:
  • Develop a basic understanding of time-resolved electrochemical surface enhanced Raman spectroscopy (EC-SERS)
  • Learn how EC-SERS provides a novel and effective screening platform for drugs of abuse
  • Discover the advantages of hyphenated EC-SERS instrumentation
Who Should Attend:
  • Anyone interested in learning how spectroelectrochemical and time-resolved techniques can be leveraged to provide reliable and effective analytical platforms
  • Anyone working in the field of forensic science
  • Anyone interested in understanding how electrochemistry and Raman spectroscopy can work together to improve detection
