In the present work the voltammetric behavior and the oxidation process of promethazine (PHZ) in electrochemical sensor based on carbon nanotubes paste containing DNA immobilized on the inorganic matrix prepared by sol-gel process (SiO 2 /Al 2 O 3 /Nb 2 O 5 ). The method of Laviron verified that the system is irreversible and high speed of electron transfer between the electrode and DNA. The study of the oxidation of PHZ and influence of pH showed slope of 0.054 V / pH (near the nernstian
