Abstract: GRAPHENE AND ITS DERIVATIVES POSSESS ELECTRONIC AND PHYSICAL PROPERTIES THAT MAKE THEM IDEAL MATERIALS FOR ELECTROCHEMICAL SENSING APPLICATIONS. THIS WORK EXPLORES THE USE OF GRAPHENE AND REDUCED GRAPHENE OXIDE (RGO) AS ACTIVE LAYERS IN A MICROELECTRODE ARRAY (MEA) PLATFORM. A NOVEL FABRICATION TECHNIQUE UTILISING NANOIMPRINT TECHNOLOGY AND BIOCOMPATIBLE MATERIALS ALLOWED FOR POTENTIAL HIGH THROUGHPUT FABRICATION OF GRAPHENE-BASED MEA SENSORS. IN ORDER TO MAINTAIN THE ADVANTAGEOUS PROPERTIES OF AN MEA SUCH AS GREATER SIGNAL TO NOISE RATIOS, USAGE IN HIGHLY RESISTIVE ENVIRONMENTS, AND GREATER SENSITIVITIES AS COMPARED TO ITS MACROELECTRODE COUNTERPART, THE OPTIMIZATION OF THE INTERELECTRODE SPACING OF GRAPHENE-BASED MICROELECTRODE ARRAYS WAS PROBED TO MAXIMIZE SENSOR PERFORMANCE WITHOUT COMPROMISING MEA BEHAVIOR. LASTLY, AN RGO NANOCOMPOSITE WAS INVESTIGATED. THE NANOCOMPOSITE WAS BIOCOMPATIBLE, ABLE TO UNIFORMLY COAT LARGE AREAS, INCREASED DEVICE SENSITIVITIES AND COULD SELF-ASSEM
