- Carbon Fibres Used As Electrode Tools For Micro
Carbon-fiber microelectrodes (CFMEs) were introduced nearly thirty years ago when Pujol and colleagues first used them with normal pulse polarography to measure the oxidation of several neurotransmitters, including dopamine, norepinephrine and serotonin. 1 Today, the most popular applications for carbon-fiber electrodes are still as sensors for …

Carbon fiber is one of the most commonly used carbon-based microfiber electrodes (Chen et al., 2020), which were first developed in the late 1970's (Santos et al., 2008). They have low cost, and can be prepared with porous structures, therefore with large surface areas (Roeser et al., 2013).

1 Introduction. Bipolar electrochemistry (BPE) is a well-established wireless technique in virtue of the faradic reactions at the two poles of a conductive object polarized in a electric field. 1 The usual setup for BPE contains a pair of feeder electrodes physically connected with the both ends of a power supply and a conductive object (called as …
