Abstract

Carbon composite electrodes are frequently used for enzymatic electrodes but suffer from poor electrocatalytic activity and/or are single use. Our group has recently developed thermoplastic electrodes (TPEs) that use a thermopolymer binder. The electrodes can be easily molded without extensive use of organic solvents enabling catalysts and enzymes to be added directly to the electrode material. The TPE material is bulk-modified with cobalt phthalocyanine and glucose oxidase, resulting in a robust sensor that is stable for over 100 minutes. These sensors can be molded into intricate shapes and sanded for surface renewal, allowing the sensors to be continuously reused.
