Biofunctional Electrolyte‐Gated Organic Field‐Effect Transistors

This is the authors' abstract. We don't add key points for this paper.

The surface modification of solution-gated organic field-effect transistors is investigated. The introduction of different surface groups leads to a control of the pH sensitivity, determined by the pKa value of the added surface moiety. Together with the successful demonstration of enzyme modification of the surface, this work reveals the large potential of organic SGFETs for biosensor applications.
