CID to Go HighTech With This Nanomaterial For Better Fingerprint Analysis
Often at a crime scene, fingerprints are the most crucial aspect that aid the investigating officers in cracking the case. But what is left out is – Invisible fingerprints which often goes undetected due to lack of advanced techniques used till date. Also at times, it becomes extremely difficult to analyze the normal fingerprints which are unclear. A group of Indian researchers is here to the rescue with a novel nanomaterial that will overcome such difficulties and also make the process of reading latent fingerprints faster.
The nanomaterial is made up of semiconductor particles which are smaller than a millimeter. All that needs to be done by the investigating officer is, scatter the nanomaterial on the surface where the fingerprint has been left behind and capture the image using the UV lamp and process it to reconstruct the fingerprint. By doping manganese and copper atoms on zinc sulfide nanosystem the new material has been developed.
Minute patterns of fingerprints such as island, fork, core and two months old fingerprints can be identified by the nanoparticle. For the experiment, the team captured fingerprint images on different surfaces with the help of a smartphone.
The Team is further planning to enhance the light emission efficiency of the nanomaterial. They also have plans to develop a smart mobile device for online retrieval of information and identification of latent fingerprints.
