This paper reports a micro-machined piezoelectric membrane-based biosensor array for immunoassay. Goat immunoglobulin G (IgG) and HBsAg were immobilized as the probe molecules on the square piezoelectric membranes of the sensors that have dimensions of 3.5 microm x 500 microm x 500 microm. Due to the mass sensitive nature of these sensors, their resonant frequencies were depressed after the anti-goat IgG or anti-HBsAg was captured by the goat IgG or HBsAg. The resonant frequencies of the… CONTINUE READING
