Proteomics in forensics: from source attribution to reconstruction of events #researchawards

Proteomics, the large-scale study of proteins, is emerging as a transformative tool in forensic science. Unlike DNA, which provides genetic identity, proteomics offers insight into biological function, tissue type, and environmental interactions. In forensics, protein analysis aids in source attribution by identifying body fluids, tissue types, or even species origin when DNA is degraded or absent. Additionally, proteomics contributes to event reconstruction, revealing time since deposition, environmental exposure, and contextual details of biological traces at crime scenes. With advances in mass spectrometry and bioinformatics, proteomic approaches are expanding the forensic toolkit, enhancing both accuracy and reliability in criminal investigations.
