METHOD FOR DETECTING TRACE EXPLOSIVES USING NANOPARTICLES

Abstract

ABSTRACT A method (100) for detecting trace explosives using nanoparticles, the method (100) comprising: synthesizing nanoparticles with high surface area and reactivity; functionalizing the nanoparticles to selectively bind with explosive compounds; exposing the functionalized nanoparticles to a sample; detecting the presence of bound explosive compounds through changes in optical, electrical, or magnetic properties of the nanoparticles; and analyzing the detection signal to determine the presence and concentration of trace explosives.
