Cyclic voltammetric analysis of pyrrole-N-vinyl carbazole copolymer and ZnO nanocomposite for the sensing of 6-TG

Abstract

Cyclic Voltammetry (CV) is an electro analytical technique that gives information about the redox behaviour of the analyte at a particular interface. Conducting polymers (CPs) are much explored sensor materials due to their unique properties such as, tunable conductivity, structural versatility, stability and multiple synthetic pathways. In the present work, investigations on the sensing ability of neat copolymer (Py-NVK) and ZnO nanocomposite (Py-NVK_ZnO) for 6- thioguanine (6-TG) anti-cancer drug molecule through the cyclic voltammetry method have been reported. The investigations have revealed that the ZnO nanocomposite is a better sensor material in terms of current-voltage for the detection of 6-thioguanine anti-cancer drug molecule in comparison to neat copolymer.
