Nano-zinc yields clearer fingerprints
Abstract:
A powder made up of zinc oxide nanoparticles can give crime fighters a clearer image of fingerprints, even on wet surfaces, say Australian researchers.
Dr Andrew McDonagh and colleagues, of the Centre for Forensic Science at the University of Technology, Sydney (UTS), report their findings in the Journal of Material Science.
McDonagh says traditional powder reveals fingerprints by sticking to the oily residues left on the surface - but this doesn't always work.
Elusive fingerprints include those found on wet surfaces such as sinks or bath tubs, especially when part of the print has been washed away.
Working with the Australian Federal Police, McDonagh and team tested a new fingerprint powder based on zinc oxide nanoparticles on surfaces such as glass, polyethylene and aluminium.
