Abstract:The interface between an electrode and a liquid plays a critical role in the overall performance of electrochemical biosensors. Surface morphology and roughness affect key parameters, such as the active area, diffusion profiles, and apparent electron transfer kinetics, whereas porosity may hinder the diffusion of fouling proteins. However, there is no simple and rapid method compatible with photolithographic electrodes to generate both nanostructured and porous surfaces. Herein, we demonstrate the interplay be… Show more
