Agnieszka Banas and Mark Breese from the National University of Singapore, and colleagues from Singapore and the UK have discovered there is more to be revealed in fingerprints. The non-destructive technique of synchrotron radiation-based Fourier transform infra-red (SR-FTIR) micro-imaging has been used to explore the molecular chemistry within the microstructures of microscopic particles found within latent fingerprints. Fingerprints can be contaminated with all sorts of things that a person has come in contact with, like powders, creams, medications and high explosive materials.
