Developing a method for the rapid detection of gunshot residue using Raman spectroscopy – Complete Phd and Masters Thesis

[ad_1]

Introduction

Gunshot residue (GSR) analysis is a critical aspect of forensic science, particularly in the investigation of firearm-related crimes. Traditional methods for GSR detection are time-consuming and labor-intensive, often requiring complex sample preparation and analysis techniques. Raman spectroscopy has emerged as a promising alternative for rapid and sensitive detection of GSR, offering the potential for on-site analysis with minimal sample preparation.

This thesis aims to develop a method for the rapid detection of GSR using Raman spectroscopy. The research will focus on optimizing the parameters for sample preparation, data acquisition, and analysis to improve the sensitivity and specificity of GSR detection. By developing a rapid and reliable method for GSR analysis, this research has the potential to significantly enhance the capabilities of forensic investigators in gun-related cases.

Thesis Overview

Gunshot residue (GSR) analysis plays a critical role in forensic investigations, aiding in the identification of firearm usage and linking suspects to crime scenes. Traditional methods for GSR detection are often time-consuming and require specialized equipment and expertise. Raman spectroscopy has emerged as a rapid and sensitive alternative for GSR analysis, offering the potential for on-site detection with minimal sample preparation.

This thesis focuses on developing a method for the rapid detection of GSR using Raman spectroscopy. The research aims to optimize the sample preparation, data acquisition, and analysis parameters to improve the sensitivity and specificity of GSR detection. By leveraging the unique capabilities of Raman spectroscopy, this study seeks to enhance the efficiency and accuracy of GSR analysis, thereby facilitating faster and more reliable forensic investigations in gun-related cases.

Through a comprehensive review of existing literature, the thesis will provide insights into the current challenges and limitations of GSR analysis, highlighting the potential of Raman spectroscopy as a leading technology in forensic science. The research methodology will outline the experimental design, sample collection, instrumentation, data analysis, and validation procedures used to develop the proposed method for GSR detection.

The discussion of findings will present the results of the study, including the optimization of sample preparation, sensitivity and specificity of GSR detection, comparison with traditional methods, validation of the Raman spectroscopy method, and potential applications in forensic investigations. The conclusions drawn from the research will emphasize the contributions of this study to forensic science and recommend future research directions to further enhance the capabilities of GSR analysis using Raman spectroscopy.

In conclusion, this thesis aims to advance the field of forensic science by developing a rapid and reliable method for GSR detection using Raman spectroscopy. By improving the efficiency and accuracy of GSR analysis, this research has the potential to significantly impact the practice of forensic investigations and contribute to the advancement of criminal justice systems worldwide.
