Recent Trends in Therapeutic and Electroanalytical Applications of Boron-Doped Diamond Sensors

Abstract:: In recent years, research and development efforts have been heavily focused on conductive diamond electrodes for electrochemical applications. Such initiatives may have been spurred by their broad potential window, low background current, chemical inertness, and mechanical robustness. Compared to other carbon-based materials, conducting diamond can oxidize several analytes before the breakdown of water in aqueous electrolytes. Since the evolution of oxygen and hydrogen does not obstruct the analysis, this is significant for the detection and/or identification of species in solution. As a result, conductive diamond electrodes expand the application of electrochemical detection and make it possible to use them for analytes that are incompatible with traditional electrode materials. Fabricating boron-doped diamond films via chemical vapor deposition on different substrates is of special interest. This article highlights the therapeutic and electroanalytical applications of boron-doped diamond electrodes in various aspects in addition to the synthetic strategies to obtain Boron Doped Diamond Electrodes (BDDE), the cost-effectiveness of BDD and its in-vivo compatibility that will help the analytical researchers to learn almost everything about the previous studies done on BDDE and encourage them to work more efficiently in this research field.
