Nanotechnology used for fingerprint checks
Abstract:
Even though the fingerprints may have dissolved or faded, with nanotechnology, forensic officials can still get a print to make further criminal traces.
To enhance the fingerprint verification process, a research team at the Asian Institute of Technology (AIT) has developed a method to use nanotechnology to get a fingerprint, even if the print has faded.
The project is part of nanotechnology development projects supported by the Nanotechnology Centre (Nanotec) under the National Science and Technology Development Agency. AIT is also one of Nanotec's eight centres of excellence for nanotechnology development.
Nanotec's director Wiwut Tanthapanichakoon said the project was to adopt nanotechnology to develop a new method to enhance the forensic fingerprint process. It uses nano-sized bioadhesive chitosan combined with gold nanoparticles to develop a new substance that could capture a fingerprint.
