Abstract

We present the fully-printed manufacturing of a biologically-functionalized organic electrochemical transistor (OECT). The channel and the electrodes (source, drain and gate) are based on PEDOT:PSS ((Poly(3,4-ethylenedioxythiophene):Polystyrene sulfonate)) deposited by inkjet printing. Murine monoclonal antibodies (mAbs) directed against ovalbumin epitopes printed on top of the semiconducting polymer channel should be able to detect ovalbumin antigens in biological solutions. First tests performed with a saline electrolyte confirm the transistor behavior of the printed OECT before and after antibodies patterning.
