A new nanomaterial developed by a group of Indian scientists promises that these difficulty will be overcome and latent fingerprint reading will also take place more quickly. The nanomaterial is luminescent and consists of semiconductor particles which are a million times smaller than a mm. All one must do is: sprinkle the nanomaterial on the surface of a fingerprint, capture the image and use a UV lamp and process it for fingerprint reconstruction.

Researchers stated that the use of mobile phones and forensic laboratories from all criminal scenes can also capture such fingerprints. Human fingerprint is a unique fingerprint in its grid patterns. When human fingers touch a surface, secretions that occur in the skin surface are transferred to the surface and leave an impression of the motive of the ridge.

Mn and ZnS Nanoparticles Used in Material

Doping manganese and copper atoms on the zinc sulphide nanosystem has developed this new material. The researchers could change the optical properties of the zinc sulfide nanosystem by replacing zinc atoms with those of copper and manganese. The strong visible luminescence property of this material is used on latent fingerprints to decipher fingerprints.

The researchers are planning to improve nanomaterial light emission efficiency and also to develop intelligent mobile devices for online data retrieval and latent fingerprints for use in the forensic sector. The new material was also used by the group to develop white LEDs.
