ABSTRACT
This article reports that Scottish researchers are developing a hand-held Terahertz (THz) device to identify illegal drugs concealed within clothing, plastics, and potentially inside the human body. Researchers at the University of St. Andrews will next year build and test a prototype, based on an improved method of generating THz waves, in collaboration with crime science and technology specialist Forensic Alliance. The team hopes that the use of THz waves will allow them to produce a portable device capable of distinguishing between different drugs, by detecting variations in frequency absorption between one type of molecule and another.
