This Review surveys the fabrication methods reported for both single microband electrodes and microband electrode arrays and their uses in sensing applications. A theoretical section on band electrodes provides background information on the structure of band electrodes, their diffusional profiles, and the types of voltammetric behavior observed. A short section summarizes the currently available commercial microband electrodes. A section describing recent (10 years) sensing applications using band electrode is also presented.
Keywords: band fabrication; biosensors; chemical sensors; high signal-to-noise ratio; low detection limits; microband arrays; microband electrodes; voltammetric response.
