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 V.A. Buzanovskii Development results of gas chemical nanosensors with sensitive elements based on carbon nanotubes during last ten years are submitted. The systematization of developed devices according to construction features of their sensitive elements is carried out. The analytical opportunities of these nanosensors are determined and the existing regularities are marked. In particular, the ability of gas chemical nanosensors with sensitive elements based on carbon nanotubes for a determination of the big number of organic and inorganic chemical compounds is demonstrated. The influence of thickness, morphology and composition of a covering of sensitive elements of these devices on sensitivity and selectivity of carried out measurements, response time, recovery time and other technical characteristics of nanosensors is shown. Key words: single-walled carbon nanotube, multi-walled carbon nanotube, gas chemical nanosensor, sensitive element, covering, metrological characteristic.
