In recent years, several approaches have been developed to biologically relevant sensing of analytes or to the diagnosis of living cells. For these applications, there is considerable demand for small portable and lowcost devices that can be used under clinical conditions. Organic semiconducting materials can provide higher sensitivity of transistors compared to conventional devices and allow the use of different architectures than standard semiconductor transistors (MOSFETs) such as ion-sensitive organic field transistors (ISOFETs), organic electrochemical transistors (OECT) and electrolyte grounded transistors (EGOFET). This ability is very attractive to create a functional interface with living cells. Biocompatibility study (Fig. 1) and study of the electrical properties of poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) and organic semiconductors were performed. It has been found that PEDOT:PSS thin films without additive or any thin film after treatment provide limited conductivity and stability for use in biomedical applications. Addition or subsequent treatment with ethylene glycol in combination with thermal annealing provided thin layers with electrical resistance and stability sufficient for use in sensing animal cell physiology. The electrical properties of DPP were studied using the OFETs transistor model. In particular, it has been investigated under what conditions the maximum mobility of the charge carrier can be achieved. By using the cumulative effect of self-assembled monolayers on dielectrics and electrodes and detailed thermal analysis of DPP, higher charge carrier mobility than previously (5.5· 10-3 cm2/Vs) was achieved.
