Nano Technology Can Restore Fingerprints

Australian researchers have developed new ways to recover fingerprints from the evidence that has been long. The scientists at the University of Technology in Sydney sure are the world's first discovery that could help police solve mysterious cases.

They are using nanotechnology to detect fingerprints are dry and brittle which can not be read by traditional techniques. Their goal is to detect the human fingerprint any age and in any surface. Specimens that were previously invisible are now available using the new chemicals that lead to amino acid.

These molecules are usually found in the sweat and therefore there is in most prints. The use of amino acids in fingerprint recognition has been used for several decades. However, researchers in Sydney using nanotechnology to observe the sample were more detailed.

"If we get way better and be able to see better long trail of evidence, there is potential for use in a variety of old cases," said Dr Xanthe Spindler told BBC Indonesia, on Tuesday (7 / 6).

"So I think this finding something that would go beyond what is used now and expect more to know and expect fingerprints also improves the success rate in solving various problems," he continued.

This research is still ongoing and Dr Spindler says an important step towards an attempt to conquer one of the major goals of forensic science that is found fingerprints from human skin. This project is collaboration between academics in Sydney, Canberra, Australian Federal Police and the University of Northern Illinois in the United States.
