摘要
Microelectrodes are a type of electrode with microscopic dimension, and due to their rapid diffusing rates, high electrical current densities and signal-to-noise ratios, they can help improve the detection sensitivity for various analytes [1]. Investigations on the fabrication and the application of microelectrodes are highly relevant. Fiber-type microelectrodes with one-dimensional (ID) microstructures that possess ID diffusion, particularly carbon fiber microelectrodes, have been widely fabricated and used in many different types of sensors due to their low cost, small volume, portability, and good biocompatibility [1,2]. However, poor electrocatalytic activity and low response currents preclude the applications of carbon fiber microelectrodes in sensors.
