Abstract

Smart (Nano) materials with biosensing functions posses enormous potential in the development of new generation stable biosensors, chemical sensors, and actuators. Recently, there is a considerable interest in using TiO2 nanostructured materials as a film-forming material since they have high surface area, optical transparency, high bio-compatibility, and relatively good conductivity. In this work, TiO2 oxides were used as nanoporous electrodes to study the electron transfer mechanisms of H2O2 and many interesting biological molecules, as 3,4-dihydroxyphenylacetic acid (DOPAC), ascorbic acid, guanine, L-tyrosine, acetaminophen, and beta-NADH, in order to assemble a new generation of chemical sensors and biosensors. A kinetic study was also reported in this paper, which demonstrated high performances towards electrocatalytic processes, obtained at nanostructured TiO2-modified electrodes (literal)
