Highly sensitive fingerprint technique developed
Researchers in the United Kingdom and France have developed a new and extremely sensitive method for visualizing fingerprints left on metal surfaces such as guns, knives, and bullet casings. The technique utilizes color-changing fluorescent films and the team says that it can be used to complement existing forensic processes. An Institute of Physics (IOP) release reports that the chance that two people will have identical fingerprints is about 64 billion to 1, which is why law-enforcement agencies rely on fingerprint evidence. Despite advances in detection since the nineteenth century, only about 10 percent of crime-scene fingerprint images are of sufficient quality to lead to the unambiguous identification of an individual that is good enough to satisfy a court.
Fingerprints are essentially deposits of sweat and natural oils. Traditional visualization techniques involve applying a colored powder, chemical or biological reagent that adheres to or interacts with the residue and creates a visual contrast to the underlying surface. A major limitation of the technique is that these deposits can degrade with time or exposure to water or other materials.
