Abstract
Screen-printed electrodes have become an essential tool in the development of electrochemical sensors and biosensors. Among the materials used for the fabrication, the most employed are the different forms of carbon. In this work, the electrochemical characterization of ordered mesoporous carbon screen-printed electrodes is carried out. The results show that the surface area is enhanced and the resistance to the electron transfer is highly reduced in comparison to graphite screen-printed electrodes. Although a lower limit of detection is obtained for screen-printed graphite, ordered mesoporous carbon electrodes showed a better voltammetric selectivity.
