CARBON-BASED ELECTRODES WITH GRAPHENE MODIFICATION

摘要

Certain embodiments of the present application describe a carbon-based electrode with graphene platelets. The addition of graphene platelets is intended to improve properties of the electrode. These properties include, but are not limited to, physical, electrical, and biochemical properties of the electrode. Enhanced reproducibility of these properties can also result from the addition of the graphene platelets.
