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 p Ka 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.
