Invisible fingerprints accidentally left behind by criminals are often difficult to decipher because available techniques can’t capture all the nuances in them. At times, they may be unclear because of damaged fingers.
A new nanomaterial developed by a group of Indian scientists promises to overcome such difficulties and also make the process of reading latent fingerprints faster.
The nanomaterial, consisting of semiconductor particles that are a million times smaller than a millimetre, is luminescent.
All one will need to do is: sprinkle the nanomaterial on the surface where fingerprint has been left behind, capture the image and use a UV lamp and process it to reconstruct the fingerprint.
Researchers said that such fingerprints could be captured using a mobile phone too and transmitted to forensic lab from any crime scene.
The new material has been developed by doping manganese and copper atoms on zinc sulphide nanosystem
