Nano technology is having huge
applications in forensic department as it helps in the diagnosis and examining
of samples at a nano-scale level. Integration of nano- technology with finger
prints produces wide range of implications and
enhances the clarity of finger prints. For example, clarity of latentfinger prints can be improved by using golden- nano particles. Aqueous solution
of silver nano-particles is used for the investigation of amino acids present
on the fingers and the modified golden nano-particles were used for sedum based
investigation. Engineering of new nano-particles will help the development of
advanced techniques for forensic investigation.
