Density Functional Theory in Forensic Science: Applications and Challenges

Wiley Interdisciplinary Reviews Forensic Science, Год журнала: 2025, Номер 7(1)

Опубликована: Янв. 20, 2025

ABSTRACT Forensic science is evolving to tackle increasingly complex criminal investigations, where traditional methods may fall short. This review examines how computational chemistry enhances forensic techniques by providing detailed insights into molecular interactions, reaction mechanisms, and spectroscopic properties. A particular focus placed on density functional theory (DFT), which has emerged as a powerful, cost‐effective tool that balances efficiency accuracy, making it ideal for studying wide range of compounds without the need physical samples. Applications discussed include analysis new psychoactive substances (NPS), detection food adulterants, development chemical sensors, examination luminol blood detection, fingerprint visualization, explosives. Key advances in various DFT functionals are highlighted, along with prospects integrating machine learning sustainable practices further expand its impact science.
