Latent fingerprints are one of the most important forensic pieces of evidence in criminal investigations due to their uniqueness and persistence throughout an individual’s life. Technological developments in latent fingerprint detection and analysis methods have advanced significantly, especially through the application of nanotechnology, artificial intelligence and spectroscopic techniques. This study aims to systematically evaluate innovations in latent fingerprint detection methods that have been developed between 2015 and 2025. The literature review shows that the integration of nanoparticle-based technologies, optical sensors and digital image processing has improved the sensitivity and effectiveness in latent fingerprint visualisation. In addition, Artificial Intelligence (AI), especially deep learning and machine learning, has accelerated and improved the accuracy of matching fingerprints with forensic databases. However, while these innovations offer more adaptive and efficient solutions, challenges remain, especially in the aspects of method standardisation, technology scalability as well as cost-effectiveness. With a multidisciplinary approach combining chemistry, physics and artificial intelligence, this research highlights the potential for developing more advanced, efficient and environmentally friendly latent fingerprint identification methods. © (2026), (Asian Publication Corporation).
