Electrode capable of high-sensitivity measurement using the redox cycle.
The comb-shaped electrode generates electrochemical redox cycle reactions on the electrode by arranging two electrodes (the generator electrode and the collector electrode) in conjunction with a collection of band electrodes. When such redox cycling occurs, the apparent current value increases, enhancing sensitivity.

basic information
The comb-shaped electrode is an electrode developed for trace electrochemical measurements by the NTT Life Environment Technology Research Institute (now NTT Environmental Energy Research Institute). Electrochemical analyses using the comb-shaped electrode have been reported for the detection of ultra-trace substances and the observation of reaction behaviors. This comb-shaped electrode is made by fabricating a microelectrode pattern on an insulating substrate using lithography techniques. The electrode structure is shown below. The number of comb teeth is 65. Each electrode functions as an oxidation electrode or a reduction electrode. Types of electrodes: Comb-shaped electrode Au width 10μm spacing 5μm Comb-shaped electrode Au width 3μm spacing 3μm Comb-shaped electrode Au width 2μm spacing 2μm Comb-shaped electrode Pt width 10μm spacing 5μm Comb-shaped electrode Pt width 3μm spacing 3μm Comb-shaped electrode Pt width 2μm spacing 2μm Comb-shaped electrode ITO width 10μm spacing 5μm *1 The narrower the spacing of the comb, the higher the sensitivity. *2 Comb-shaped electrodes without an insulating film are also available.
