Despite its limited applications, nanotechnology has made signifcant contribution in a broad scientifc arena. Te technology is concerned with the development of new materials and reagents with conventional characteristics. Nano-particles are made from a variety of substances such as biopolymers, and synthetic polymers. Te nano-particles synthesized from bio-polymers have benefts over synthetic polymeric nano-particles which include biocompatibility, non-toxicity, cost-efciency and bio-degradability. Te use of nano-particles have gained a lot of attention in recent years. Te use of the bio-polymeric nanoparticles provides new opportunities in surface-based applications. Te fngerprint detection is based on surface phenomena to which nanotechnology can be applied. Tis article reviews the forensic application of bio-polymeric nano-particles and their use in development and enhancement of latent fngerprints. Te use of nano-particles has emerged as a powerful tool for improved forensic analysis. It also provides deep insight into the future possibilities of
nanotechnology.
