Reversible switching of the electrode interface between OFF/ON states is achieved by electrochemically triggered reorganization of a nanostructured polymer brush associated with the interface. The switching process is accomplished by local interfacial pH changes allowing operation in buffered biological environments (see figure). The fabricated device mimics the performance of switching electronic devices such as transistors.
