News Academy of Engineering Sciences A.M. Prokhorov Annotation << Back Gas chemical nanosensors with sensitive elements based on carbon nanotubes. Analysis of development during last years. Part 1 V.A. Buzanovskii Results of development during last ten years of gas chemical nanosensors with the sen-sitive elements based on carbon nanotubes are submitted in the review. The developed devices are systematized according to construction features of their sensitive elements. Thus four nanosensor groups are defined. Group 1 is devices sensitive elements of which have a covering only from carbon nanotubes. Group 2 is nanosensors with the sensitive elements containing a covering from carbon nanotubes and an external layer of other material. Group 3 is devices sensitive elements of which have a covering from a composite based on carbon nanotubes. Group 4 is nanosensors with the sensitive ele-ments containing a covering from a composite based on carbon nanotubes and an exter-nal layer of other material. Construction features and analytical abilities of devices of group 1 are demonstrated in the first part of the review. The second part of the review is devoted to consideration of construction features and analytical abilities of the nanosen-sors that are included in groups 2, 3 and 4. Key words: single-walled carbon nanotube, multi-walled carbon nanotube, gas chemical nanosensor, sensitive element, covering, metrological characteristic.
