Thin Film Interdigitated Micro-Array Electrodes

IDA: Thin film Interdigitated Micro-array Electrodes on Glass

Thin-film technologies enable the integration of the reference (RE) and counter (CE /AE) electrodes with the interdigitated microelectrodes. Interdigitated array (IDA) electrodes take also advantages of the microelectrode’s features enhancing the sensitivity and detection limits. In this case, the working electrode (WE) consists of two individually addressable arrays of microelectrodes with an interdigitated approach. Thin-film IDA electrodes could be used in single- (only one WE, generator, is connected) or dual-mode (both WEs, generator and collector, are connected). Dual-mode enables the microelectrode behavior, reaching the steady-state in a short time and enhancing the analytical signals. Different IDA microelectrode (WE1/WE2) designs are available in platinum or gold.
