This paper reports pyrolyzed polymer as an ^<18>F^- deposition and recovery electrode for positron emission tomography (PET) application. The electrochemical separation of ^<18>F^- from H_2^<18>O water has been studied for preparation of a PET probe. We apply μTAS technology to provide an integrated cell system. This study proposes a pyrolyzed polymer electrode instead of conventional bulk glassy carbon (GC) electrode. A pyrolyzed polymer electrode can be batch fabricated using MEMS technology. The deposition and recovery yield of the pyrolyzed polymer electrode derived from the photoresist (AZ P4620) at 1000℃ was estimated to be 77% and 38%, respectively. Furthermore, we propose a composite of pyrolyzed polymer and GC particles to take advantage of both materials. This paper evaluates developed electrode for PET application.
