Abstract

Chemical sensors has received widespread attention during the past two decades because of their rapid, accurate, reproducible, and low-cost methodologies. Carbon paste electrodes (CPEs) are suitable for a variety of applications and many works have been devoted in the development of new sensitive and selective electrode surfaces based on carbon paste. The application of novel and promising carbonaceous materials, as electrode surfaces, is an issue of great concern. <BR />In this work, the immobilization of calf thymus dsDNA on alternatively prepared carbonaceous materials is being demonstrated. The alternatively prepared carbonaceous materials that were used was activated carbon (B), HNO₃ oxidized activated carbon (B5), Ag impregnated activated carbon BAX-Ag (B-Ag) and graphite oxide (GO). Electrochemical techniques (such as differential pulse voltammetry) were applied, aimed to the use of novel carbonaceous materials at electrochemical DNA sensing.
