Synergistic influence of structure and properties of nanomaterials in latent finger print detection: A scoping review

Latent fingerprint development techniques have been evolved with the use of methods like powder dusting, cyanoacrylate fuming, chemical methods, and application of small particle reagents. These all have been gradually compromised due to their growing drawbacks in terms of their stability, specificity and even toxicity. Nano materials have great potential in identification of latent fingerprints due to their unique optical, magnetic, electric, and other properties. Oxides, silicates and composite materials of Nano-dimensions have significant role in different areas of Forensic science. Fluorescent nanomaterial has drawn a lot of attention because of its superior optical and chemical properties. The present review has focused on exploring the magnetic, luminescent and magnetic-luminescent properties of different nanomaterials in the detection of latent finger prints. Various factors like impact of synthetic methodology, morphology and structural parameter of the nano materials on finger print visualization have also been discussed.
