News Academy of Engineering Sciences A.M. Prokhorov Annotation << Back Analysis of development of gas chemical nanosensors with sensitive elements based on copper oxides Buzanovskii V.A. Results of development of gas chemical nanosensors with the sensitive elements based on copper oxides are submitted in the review. The developed devices are systematized according to construction features of their sensitive elements. Thus, three nanosensor groups are defined. Group 1 is devices sensitive elements of which have a covering only from copper oxide. Group 2 is nanosensors with the sensitive elements containing a covering from copper oxide and an external layer of other material. Group 3 is devices sensitive elements of which have a covering from the composite based on copper oxide. Analytical abilities of the listed nanosensor groups are demonstrated. Typical regularities are marked. In particular, ability of these devices to determination of the big number of inorganic and organic chemical compounds is presented. Influence of morphology and composition of a covering and also temperature of sensitive element on sensitivity and selectivity of measurements, response time and recovery time is shown. Key words: nanotechnology, nanomaterial, gas chemical nanosensor, sensitive element, covering, copper oxide, metrological characteristic. Contacts: E-mail: vab1960@rambler.ru Pp. 29-53.
