## Abstract Two electrical methods (Faradaic impedance spectroscopy and ion‐sensitive field‐effect transistor (ISFET)) are applied to sense aptamer‐substrate complexes. The methods utilize anticocaine aptamer fragments that self‐assemble, in the presence of cocaine, to a supramolecular aptamer frag
