The results of the development of gas chemical nanosensors with sensing elements based on indium oxide are presented in the review. The developed devices are systematized in accordance with the features of construction of their sensing elements. Four groups of nanosensors are specified: devices with sensing elements containing a coating of only indium oxide (Group 1); nanosensors with sensing elements containing a coating of indium oxide with an outer layer of another material (Group 2); devices with sensing elements containing a coating of composite material based on indium oxide (Group 3); and nanosensors with sensing elements containing a coating of composite material based on indium oxide and an outer layer of another material (Group 4). The analytical capabilities of the devices of these groups are assessed. Some patterns in their behavior are discussed. In particular, the potential of nanosensors for the identification of a large number of inorganic and organic chemical compounds is demonstrated. The effect of the thickness, morphology, and composition of the coating, as well as the temperature of the sensing elements, on the sensitivity and selectivity of measurements and the response and recovery times is shown.
