Jenna: Australian Scientists from the Centre for Forensic Science at the University of Technology in Sydney are looking into the use of zinc oxide nanoparticles as a fluorescent fingerprint detection powder.
Working with the Australian Federal Police, the researchers have tested the new fingerprint powder on surfaces such as glass, polyethylene and aluminium. They have found that the nanopowder can give investigators a clearer image of fingerprints, and it even works on wet surfaces, meaning previously elusive prints, such as those on sinks and bath tubs, can now be seen.
Another benefit of the nanopowder is that it can be illuminated with ultraviolet light, making the nanoparticles fluoresce, eliminating the need to add any fluorescent dyes.
So hopefully next time they dust for prints on CSI, they will be using their bottle of zinc oxide nanopowder!!
