Controlling Inter-Sheet-Distance in Reduced Graphene Oxide Electrodes for Highly Sensitive Electrochemical Impedimetric Sensing of Myoglobin

Abstract In order to improve the sensitivity of electrochemical impedance spectroscopy (EIS)-based biosensors, a number of structuring strategies to promote enlarging the electroactive surface area have been recently proposed. However, these approaches have not been applicable to graphene-based electrodes especially due to their ultrathin film thickness (usually
