Chemist have developed device to detect microscopic signs of cancer, bombs and impure water. Both cancer cells and the chemicals used to make bombs can foil detection because they appear in trace amounts too small for conventional detection techniques. Scientists have developed the ultimate solution: a molecule that can magnify weak traces of “hidden” molecules into something we can detect and see.
