|There's a new method of fingerprinting which detects salts from sweat using X-rays. The new method has several advantages over traditional powders, liquids or vapors. It won't destroy or alter the print and can be used to take prints from difficult materials, such as wood, leather, plastic & human skin.
"This process represents a valuable new tool for forensic investigators that could allow them to nondestructively detect prints on surfaces that might otherwise be undetectable by conventional methods," said Chris Worley, who led the research. "It won’t replace traditional fingerprinting, but could provide a valuable complement to it."
