Abstract

We developed a 3D interdigitated (IDA) array electrode consisting of Au nano particles, which increase the electrode surface. The electrode was fabricated using microfabrication and printing techniques. Electrochemical impedance spectroscopy was conducted to measure IgG concentration, when anti-IgG was immobilized onto Dithiobis (succinimidyl propionate) (DTSP) SAM/3D-IDA electrode. A linear relationship between charge transfer resistance (R ct) values and the logarithm of IgG concentration was observed in the range of 1 μg/ml to 1 mg/ml.
