Green Synthesis of Nanoparticles for Enhanced Latent Fingerprint Development: A Sustainable Approach

Abstract

The development of latent fingerprints plays a pivotal role in forensic investigations by providing critical evidence for identifying individuals involved in criminal activities. However, traditional fingerprint development methods often rely on chemical reagents that are environmentally harmful and pose potential health risks to forensic investigators. In recent years, there has been a surge of interest in eco-friendly and sustainable techniques for fingerprint enhancement. Green synthesis involves the utilization of natural compounds, such as plant extracts and microorganisms, to fabricate nanoparticles with enhanced properties. These nanoparticles offer numerous advantages, including biocompatibility, cost-effectiveness, and minimal environmental impact. Furthermore, the role of different types of green-synthesized nanoparticles, such as silver, gold, and magnetic nanoparticles, in enhancing the visibility and quality of latent fingerprints. It discusses their unique properties, synthesis methods, and interactions with fingerprint residue components. It also discusses future research directions and potential advancements in this emerging field, with the aim of promoting sustainable and environmentally friendly approaches for forensic fingerprint analysis. Overall, the incorporation of green-synthesized nanoparticles in latent fingerprint development holds tremendous promise for advancing forensic science while mitigating the negative impact on the environment and human health. By embracing these eco-friendly techniques, forensic investigators can enhance their capabilities in fingerprint analysis while upholding sustainable practices. © 2026 by Apple Academic Press, Inc.
