Landmine detection: improved binding of 2,4-dinitrotoluene in a gamma-CD/metal oxide matrix and its sensitive detection via a cyclic surface polarization impedance (cSPI) method.
Highly sensitive and selective detection of 2,4-DNT, a representative explosive, was achieved by the synergic effect of molecular imprinting and host (cyclodextrin)-guest interaction in ultrathin layers of TiO(2) and SiO(2) gel; the detection limit using cSPI measurements reached nM concentration.
