Of the myriad of potential application areas commonly associated with Nanotechnology, sensors based on carbon nanotubes (CNT) and metal-oxide nanoribbons are one of the closest to commercial reality. In the quest for practical sensing devices, molecular modeling continues to provide useful insight and guidance. In this work we review some of our recent molecular modeling investigations on: (1) CNT-based electromechanical sensors; (2) gas-sensing properties of SnO2 nanowires/ribbons; and (3) CNT-metal contacts, which can significantly affect the performance of CNT-based sensors.
