DNA Fingerprints from Fingerprints: A Systematic Review

Abstract

The integration of DNA analysis with traditional fingerprint evidence has emerged as a powerful tool in modern forensic science. This systematic review examines the potential and reliability of extracting DNA profiles from latent fingerprints, with the goal of bridging the gap between two cornerstone forensic identification techniques. Through a comprehensive analysis of peer-reviewed literature, this review examines methods for DNA recovery from fingerprints, factors influencing DNA yield and quality (e.g., surface type, environmental conditions, fingerprint age), and advancements in low-template DNA analysis. It also discusses challenges such as contamination risks, degradation, and legal admissibility. Overall, the findings highlight that while DNA extraction from fingerprints is feasible and increasingly refined, it remains dependent on situational variables and technological constraints. The review concludes by recommending standardized protocols and further research to enhance the accuracy, reproducibility, and forensic utility of DNA fingerprinting from fingerprint evidence.
