Fabrication and electrochemical behaviors of thin film three electrode-measurement unit with microdisk array as working electrode

摘要

A three electrode-measurement unit with 33 microdisk electrode-array (MDA) as working electrode was constructed by lithography. Its electrochemical behavior was observed. The results of the oxidation of ferrocene in CH_3CN-H_2O mixed media demonstrate that high quality electrochemical data for the system without supporting electrolyte can be achieved with the MDA unit constructed in the present work.
