The results of the development of gas chemical nanosensors with sensing elements based on copper and nickel oxides are presented in the review. The developed devices are systematized in accordance with the construction features of their sensing elements. Both types of nanosensors are divided into three groups. The first group includes devices with sensing elements containing a coating of only copper oxide or nickel oxide. The second group combines devices with sensing elements containing a coating of a layer of copper oxide or nickel oxide with an outer layer of another material. The third group are nanosensors with sensing elements containing a coating in the form of a layer of a composite material based on copper oxide or nickel oxide. The performance characteristics of these groups of devices are considered. Some patterns in their behavior are discussed. In particular, the potential of nanosensors in the identification of a large number of inorganic and organic chemical compounds is demonstrated. The effect of the morphology, thickness, and composition of the coating and temperature of the sensing elements on the sensitivity and selectivity of measurements and the response and recovery times is shown.
