摘要

Thin-film transistors (TFTs), used as small-area, highly sensitive transducer devices for chemical and biological purposes, have attracted a lot of attention in the recent years. The integration of a TFT in a liquid environment poses two major challenges. On the one hand side, device stability in liquid has to be ensured by appropriate passivation or capping schemes. On the other hand, biocompatibility is mandatory for applications aiming on monitoring of e.g., molecule concentrations in blood or tissue. Organic semiconductors exhibit a non-toxic and most notably soft ambience to neuronal net-works and can be processed on flexible plastic substrates and organic dielectric layers. Therefore, organic thin-film transistors (OTFTs) are considered as promising candidates for biosensing.
