Organic Transistor Devices for In Vitro Electrophysiological Applications

This thesis reports on the Micro OCMFET Array, a novel, reference-less

system for extracellular recordings of action potentials. The book

provides readers with a full description of the system, together with an

extensive report of the successful experimental trials carried out on both

cardiac and nerve cells. Moreover, it offers a concise yet comprehensive

overview of both bioelectronic interfaces, such as Micro Electrode Arrays

(MEAs) and Field Effect Devices (FEDs), and organic sensors for electro-

physiological applications, including Organic Charge-Modulated FETs

(OCMFET), Electrolyte-Gated Organic FETs (EGOFETs), and Organic

Electrochemical Transistors (OECTs).

Zusammenfassung

This thesis reports on a novel system for extracellular recordings of the activity of excitable cells, which relies on an organic, charge-modulated field-effect transistor (FET) called OCMFET. The book shows how, thanks to the intrinsic biocompatibility, lightness, and inexpensiveness of the material used, this new system is able to overcome several problems typical of of classic electronic and bioelectronic. It provides a full description of the system, together with a comprehensive report of the successful experimental trials carried out on both cardiac and nerve cells, and a concise yet comprehensive overview of bioelectronic interfaces and organic sensors for electrophysiological applications.
