Globalization of terrorist attacks in recent years calls for advanced technologies to detect the concealed explosives effectively. We demonstrate a highly sensitive and selective detection of traces of nitro-aromatic explosive compounds by functionalizing gallium nitride (GaN) nanowires with titania (TiO2) nanoclusters to address this issue. The ultraviolet light photo-modulated GaN/TiO2 nanowire-nanocluster (NWNC) hybrids show remarkable selectivity to benzene and related aromatic compounds… CONTINUE READING
