Sinusoidal voltage electrodeposition and characterization of conducting polymers on gold microelectrode arrays

► We report electrodeposition of conducting polymers by using sinusoidal voltages. ► Conducting polymers were electrodeposited on gold microelectrode arrays. ► The electron transfer kinetics of redox probe at polymer surface was investigated. ► Amplitude of sinusoidal voltages influences the porosity of the polymers. ► The highest porosity was obtained at amplitude of 50 mV.
