During the last two decades, a branch of electronics based on semiconducting polymers has emerged as a basis for bioelectronic devices, with considerable advantages when compared to traditional electronic materials, such as silicon.
The soft matter nature and unique features of semiconducting polymers make them ideal for many bioelectronic applications. In this communication, we focus on a particular set of materials and devices which are being investigated in our laboratory, namely the semiconducting polymer, best known as PEDOT:PSS, and two particular kinds of devices: organic electrochemical transistors, which can act as transducers and sensors, and electrodes to induce neural stem cell differentiation.
