Scientists create a new fingerprint detection technique that makes them glow

After burglars broke into his house, Australian scientist Dr. Kang Liang was very frustrated to see that the local police couldn’t identify any fingerprints left by the criminals. So he decided it was about time to develop a new – and more efficient – crime scene identification technique for fingerprint detection and analysis.

Liang and the researchers at Australia’s CSIRO, developed a liquid containing metal organic framework (MOF) crystals which binds to the residues – such as fatty acids, proteins, peptides and salts – in fingerprints. When applied to surfaces, this liquid creates an ultrathin layer over the fingerprint, making it glow bright green in less than 30 seconds.
