Applications of tip-enhanced Raman spectroscopy in forensic science – Complete Phd and Masters Thesis



Introduction

Forensic science is a crucial field that involves the application of scientific principles to examine and analyze evidence in criminal investigations. One of the key techniques used in forensic science is Raman spectroscopy, a non-destructive analytical technique that provides information about the chemical composition and structure of materials. Tip-enhanced Raman spectroscopy (TERS) is an advanced form of Raman spectroscopy that offers higher spatial resolution and sensitivity, making it a powerful tool for forensic analysis.

This thesis focuses on the applications of TERS in forensic science, exploring how this technique can be used to enhance the analysis of trace evidence, such as fibers, paints, and drugs. By improving the spatial resolution and sensitivity of Raman spectroscopy, TERS has the potential to provide valuable information that can aid in criminal investigations and court proceedings. The research aims to demonstrate the potential of TERS as a valuable tool in forensic science and highlight its advantages over traditional Raman spectroscopy techniques.
