Gas and Biosensors Made from Metal Oxides Doped with Carbon Nanotubes

Excellent physical properties of carbon nanotubes (CNTs) are used for the manufacturing many electronic devices. The single wall version of CNTs is promising for the detection of many important gases including gases exhaled by the living organism. The most promising is the realization of gas sensors based on metal oxides doped with CNTs. Application of CNT-based sensors to breath analysis, properties of the SWCNTs gas sensors with metal nanoparticles and metal oxides, and CNTs biosensors are reviewed in this paper.
