Individual tin oxide (SnO₂) nanowires were electrically contacted with Focused Ion Beam (FIB) nanolithography techniques, their properties were characterized and their behavior as gas and ultraviolet light sensing devices was evaluated. These nanowires exhibited outstanding and reproducible responses to carbon monoxide and ultraviolet light, demonstrating that gas sensors and photodetectors based on this technology can be obtained. The combination of these nanowires with suspended microhotplates with integrated heaters is presented as a good solution to develop new nanowire-based devices.
