Forensic Chemistry Chemistry is used to analyze physical evidence collected from crime scenes by identifying its chemical composition and nature. This helps investigators establish connections between physical evidence and criminal incidents. Forensic Toxicology Chemical analyses play an important role in detecting drugs, poisons, and medications in blood, urine, and tissue samples. They also help determine their concentrations using techniques such as GC-MS and HPLC. Blood Detection Luminol is used to detect invisible or hidden blood traces through a chemiluminescence reaction, helping investigators identify possible bloodstain locations at crime scenes. Gunshot Residue Analysis Elemental analysis techniques are used to detect elements associated with firearm discharge residues, such as lead, barium, and antimony, using electron microscopy and spectroscopic techniques. Trace Evidence Analysis Chemistry helps analyze fibers, paints, glass fragments, and soil samples. Their chemical compositions can be compared using techniques such as FTIR and Raman spectroscopy to identify similarities and differences between samples. Biochemistry and Biological Evidence Biochemistry is used to analyze proteins, enzymes, and biological components in blood, saliva, and other body fluids. These analyses complement DNA techniques in human identification. Artificial Intelligence in Forensic Chemistry Artificial intelligence contributes to the analysis of chemical data and spectra and the identification of unknown compounds, improving the speed and accuracy of laboratory evidence interpretation
