About this Research Topic
Luminescence and electrochemical methods for the analysis of various types of physical evidence offer great sensitivity and selectivity. Drugs of abuse, explosives, fingermarks, metals, biological fluids, and other types of evidence can be analyzed using the proposed methods for identification and quantification purposes. These areas have tremendously grown over the last few years and significantly contributed to a better understanding of the nature of physical evidence. Additionally, improved limits of detection of targeted analytes can be achieved by integrating new materials such as nanoparticles, nanocomposites, metal-organic framework (MOFs). Luminescence and electrochemical methods can also show great potential for portability and in-field analysis and data collection a feature ideally required in modern forensic crime scene investigation.
Recent advances in fluorescence, chemiluminescence, electrochemiluminescence, electrochemical, and other sensors, have shown great potential in forensic chemistry. The small sample volume and portability of these methods have made them platforms of choice for forensic crime scene screening and investigation. However, the selectivity and stability of some reagents used in some of these methods present persistent issues. Analysis of real samples recovered from the suspect(s) or crime scenes(s) using luminescence and electrochemical methods should be further explored. The effects of contaminants, temperature, and ageing on the sample are relevant and important in forensic scenarios and are also worth investigating.
This Research Topic focuses on novel materials, miniaturization (lab-on-a-chip, lab-on-paper, lab-on-skin, and other formats), portability, and studies of forensic scenarios related to themes including, but not limited to:
- Biological fluids
- Drugs of abuse
- Metals and other types of physical evidence
- Effect of contaminants, temperature, aging, and other environmental conditions on the evidence
We welcome the following contributions: communications, review articles, perspectives, and original research papers which are relevant to the suggested topics.
Keywords: Luminescence, Electrochemical, Forensic Science, Physical Evidence, Portable Devices
