Label-free protein recognition using an aptamer-based impedance measurement assay

A novel aptamer-based biosensing assay for label-free protein detection and quantification by measuring the change in electrochemical impedance upon protein–aptamer complex formation was demonstrated. Our process starts with a self-assembly of the DNA aptamer on a microfabricated thin film gold elec...
