Project
Aims to the preparation of portable sensors for explosives based on nanostructures such as semiconductor nanowires or carbon nanotubes. This permits to prepare sensitive, very compact and lightweight chemical sensors that can be carried by unmanned vehicles such as drones to explore hazardous environments without the direct human intervention. Devices based on nanostructures have the advantage of very low electrical consumption, high chemical sensitivity, simple technology.

Nanowires (NW) based sensors
Germanium nanowire (NW) based sensor contacted between two gold contacts: explosive molecules in the air are attracted to the surface of the NW acting as a gate electrode in a field effect transistor (FET) and modifying the conductivity of the NW.
DISCOVER
Carbon nanotubes (CNT) based sensors
Carbon Nanotubes based sensor: the presence of explosive molecules in the air modifies the resistivity of the network of the nanotubes. Their surface is modified to attract explosives molecules in the air.
DISCOVERExplosives
TNT molecules , being electron deficient, tend to attract amino groups (NH2) bound to the surface of the nano sensor and changing its electrical properties
Improvised Explosive Devices (IED) loaded with TNT
