Scientists have devised a way of connecting gun crimes back to a suspect. The groundbreaking technology...Pollen. What took Mother Earth millions of years to engineer, is being used by scientists to connect suspects back to the cartridge casings used at a crime scene. Scientist have enhanced the pollen by adding their secret formula of "titanium oxide, zirconia, silica, or a mixture of other oxides." I guess the ratio of ingredients and not the actual ingredients are the secret formula.
|The tags primarily consist of naturally-occurring pollen, a substance that evolution has provided with extraordinary adhesive properties,” says Professor Paul Sermon from the University of Surrey, who has led the research. “It has been given a unique chemical signature by coating it with titanium oxide, zirconia, silica or a mixture of other oxides. The precise composition of this coating can be varied subtly from one batch of cartridges to another, enabling a firm connection to be made between a particular fired cartridge and its user.|
So in the future super sleuths, look for the suspect with the sniffles and a box of Kleenex. It could be the smoking gun ;)
