<p>Methods and apparatus for detecting the presence of explosives by analyzing a vapor sample from the suspects' vicinity utilizing at least one microcantilever (10). Explosive gas molecules which have been adsorbed onto the microcantilever are subsequently heated to cause combustion. Heat, along with momentum transfer from combustion, causes bending and a transient resonance response of the microcantilever which may be detected by a laser diode (14) which is focused on the microcantilever and a photodetector (18) which detects deflection of the reflected laser beam caused by heat-induced deflection and resonance response of the microcantilever.</p> |
