Nanomaterials for sensors

Publications of the past five years dealing with nanomaterials used as sensors for determination of gases are analysed. Peculiarities of the production of chemoresistive nanosensors based on semiconducting oxides, carbon nanotubes and polyaniline are outlined. The main application fields of gas sensors are considered. Prospects for the use of quasi-one-dimensional nanomaterials such as nanorods, nanotubes and nanobelts as the materials in sensor units are discussed.
