Criminals might not get away so easily, thanks to a new fingerprinting method that may be faster and more reliable than traditional methods, researchers say.

The method images the sweat pores in a human hand using a polymer that glows fluorescent and changes color when it comes in contact with tiny droplets of water. Only a small fraction of the fingerprint is needed to identify an individual, according to the new study.

“The sensor technology developed in this study has the potential of serving as a new method for fingerprint analysis and for the clinical diagnosis of malfunctioning sweat pores,” the researchers wrote in the study
