Tóm tắt

Redox cycling (RC) amplification has been introduced as an efficient strategy to enhance signals in electrochemical sensing at low analyte concentrations of relevant biomarkers such as dopamine. RC amplification requires closely spaced and electrically separate electrodes, preferably with nanogaps. The aim of this study was to establish a method enabling the microfabrication of carbon-based stacked-layer nanogap electrodes (SLNE) designed for RC amplification. Pyrolytic carbon was employed as the electrode material and Al
