TEST RESULTS OF A BIOSENSOR SYSTEM USED FOR THE DETECTION OF HIDDEN OPIATES.
Abstract
THE DEVICE USES A BIOLOGICAL TECHNIQUE OF VAPOR DETECTION BY WHICH LUMINESCENT ORGANISMS CHANGE THEIR LIGHT EMISSION WHEN EXPOSED IN THE PRESENCE OF A VAPOR TO WHICH THEY HAVE BEEN CULTURED AND SENSITIZED. THE BIOSENSOR IS A LIVING CONGLOMERATION OF MILLIONS OF THESE LUMINESCENT BACTERIA, PLACED IN AN AIR SAMPLER WITH AN OPTICAL TRANSDUCER TO BECOME A POTENT DETECTOR. THE DEVICE IS PORTABLE, HAND-HELD, AND REQUIRES A TRAINED OPERATOR. TESTS WERE CONDUCTED IN A VARIETY OF ENVIRONMENTAL CONDITIONS AND SEARCH SITUATIONS. TEST RESULTS IN THIS REPORT INVOLVE OPIATE DETECTION IN A HEROIN CUTTING ROOM, A WALL SEARCH, A BOX, CARGO AND LUGGAGE SEARCH, AND SEARCH OF A CLOSED ROOM. SPECIFIC FACTUAL PARAMETERS FOR EACH TEST ARE PROVIDED, AS ARE STRIP GRAPH CHARTS. SEE ALSO NCJ-011226 AND NCJ-011227. (AUTHOR ABSTRACT MODIFIED)
