Cylindrical microelectrodes fabricated from carbon fibers benefit from the properties of
microelectrodes (i.e., significant contribution of radial diffusion mass-transfer to Faradayic
current resulting in improved signal to noise ratio) and with respect to exceptional mechanical
properties of carbon fiber material represent a powerful tool for electrochemical sensing. The
carbon fiber microelectrodes’ fabrication, pretreatment protocols and modification by diverse
functional layers will be outlined in the talk. The performances of bare and modified carbon fiber
microelectrodes in amperometric sensing, FIA, microdialysis, HPLC-ED and SERS will be discussed.
