Chemical analysis in forensics: identification based on the chemical composition of blood samples and latent fingerprints

Chemical analysis plays a pivotal role in modern forensic science by providing objective, reproducible, and court-admissible data. This article explores the analytical methods used in the identification of individuals based on the chemical composition of blood samples and latent fingerprints. Techniques such as chromatography, mass spectrometry, and spectroscopy allow for detailed profiling of biological evidence. Blood analysis enables determination of genetic identity, drug presence, and disease markers, while fingerprint chemistry can reveal substances excreted through sweat and contaminants associated with the individual. This integrative approach enhances the precision of forensic investigations and supports the broader goal of justice through science.
