Abstract:
The use of chemiresistors for developing devices for the point-of-care is highly attractive because of their inherently compact and simple design. The basic chemiresistor architecture, consisting of two electrodes connected by an electronically conductive channel, is a key feature compared to other technologies such as organic electrochemical transistors (OECTs). In this work a paper-based chemiresistive sensor is proposed, in which the conductive channel consists of a PEDOT:PSS-Pt nanoparticles composite. The device has been optimized and tested first for the detection of hydrogen peroxide and later, after proper biofunctionalization with glucose oxidase enzyme, for the determination of glucose in aqueous environment.
