The Organic Charge-Modulated Field-Effect Transistor: a Flexible Platform for Application in Biomedical Analyses

S. Lai, A. Spanu, P. Cosseddu, A. Bonfiglio

Organic device-based sensors are currently being extensively investigated as key elements in easy-to-use, portable platforms for life science and healthcare. Filling the gap between laboratory environment and real application scenarios poses several challenges that researchers must address in order to meet the requirements for the realization of low-cost and efficient devices for Point-of-Care applications. Here we report a specific device architecture, namely the Organic Charge-Modulated Field-Effect Transistor (OCMFET), that represents a convenient option for the development of several kinds of electronic biosensors and bio-interfaces. A complete description of the OCMFET working principle will be provided, as well as its peculiar properties, which make it a unique device in the (bio)sensing field. Application of OCMFET principle for biochemical and biophysical sensor will be also discussed.
