Аннотация:We have demonstrated that electrolyte-gated organic fi eld-eff ect transistors (EGOFETs)with the semiconductor layer based on [1]benzothieno[3,2-b]benzothiophene and thereceptor layer containing 4,13-diaza-18-crown-6 ether can be used as sensors for sodiumor potassium ions in solution. The proposed method for fabrication of the receptor layerallows developing a universal platform for the detection of various metal ions using crownether structures. The EGOFETs with the receptor layer described in this work can operatein electrolyte solutions of high ionic strength, thus providing the possibility to detect sodium and potassium ions in real biological fl uid samples.
