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.
研究了溶液门控有机场效应晶体管的表面修饰。通过引入不同的表面基团,可以控制 pH 灵敏度,这取决于添加的表面基团的 pKa 值。结合对表面进行酶修饰的成功演示,这项工作揭示了有机 SGFET 在生物传感器应用方面的巨大潜力。
