Alternate hot and cold electrodes, actively heated and chilled, were facilely fabricated for the first time. It consists of two symmetrically placed semiconductor thermoelectric coolers and an embedded interlayer with a Pt-PtRh thermocouple. The tip of Pt-PtRh thermocouple can be used as both an electrochemical electrode and a temperature-sensing device simultaneously. Theoretical simulation shows that a local steady-state supercooled water within a radius of ca. 12.6 mm around the electrode can be obtained. In this paper, the activity of horseradish peroxidase is evidenced at supercooled temperature (-9 degrees C) in 0.1 M PBS.
