Дан обзор научных публикаций последних лет, посвященных вопросам создания газовых и электрохимических сенсоров, в том числе биосенсоров, на основе углеродных нанотрубок. Представлены результаты экспериментального и теоретического изучения принципов и механизмов их работы. Описаны особенности строения углеродных нанотрубок. Рассмотрены основные закономерности структуры, энергетических характеристик и сенсорных свойств модифицированных полупроводящих систем на основе углеродных нанотрубок. Представлен анализ механизмов взаимодействия нанотубуленов с функциональными группами (в том числе, карбоксильной и аминной), металлическими наночастицами и полимерами, приводящих к образованию химически активных зондов для сенсорных устройств. Обсуждена возможность применения гранично−модифицированных однослойных углеродных нанотрубок для идентификации металлов. Представлены результаты компьютерного моделирования взаимодействия нанотрубок, гранично−модифицированных группами —СООН и —NH2, с атомами и ионами калия, натрия и лития. Расчеты выполнены в рамках моделей молекулярного кластера с использованием расчетных методов MNDO и DFT. Построенные подобным образом сенсоры могут быть использованы для установления наличия и идентификации как собственно металлических атомов, так и их ионов, входящих в состав солей и щелочей.

A review of publications over the last years dealing with the development of gas and electrochemical sensors, including biosensors, on the basis of carbon nanotubes is provided. Results of the experimental and theoretical study of their principles and operation mechanisms are provided. The structure of carbon nanotubes has been described. The main regularities of the structure, energetic characteristics and sensor properties of the modified semiconducting systems on the basis of carbon nanotubes have been studied. Analysis of the mechanisms of the interaction between nanotubes and the functional groups (including carboxyl and amino ones), metal nanoparticles and polymers for the formation of chemically active sensors has been reported. The possibility of application of the boundary modified monolayer carbon nanotubes for the identification of metals is discussed. Results of simulation of the interaction between nanotubes boundary modified by —COOH and —NH2 groups with atoms and ions of potassium, sodium and lithium obtained using the molecular cluster model and the MNDO and DFT calculation methods are provided. The sensors synthesized in this way will be used for establishment of the existence and identification of metal atoms and their ions included in salts and alkalis.
