Abstract:
1. A method of determining a presence and/or an amount of a nitro-containing explosive is a sample, the method comprising contacting the sample with a device comprising a semiconductor nanostructure and a functional moiety attached to said nanostructure, said functional moiety being an electron-donating moiety, interacts with the nitro-containing explosive by forming a charge transfer complex, and has a length smaller than 2 nm, said nanostructure being selected from a nanowire and a nanotube, and is being disposed between a source electrode and a drain electrode, such that upon contacting a sample that contains the nitro-containing explosive, a detectable change in an electrical property of the nanostructure is exhibited, said change being indicative of the presence and/or amount of the nitro-containing explosive in the sample.
