Graphene field effect transistors for bioelectronic applications

The development of the future generation of neuroprosthetic devices will require the advancement of novel solid-state sensors with a further improvement in the signal detection capability, a superior stability in biological environments, and a more suitable compatibility with living tissue. Due to the maturity of Si technology, Si-based MOSFETs have been extensively used in previous decades for these applications. However, several disadvantages of Si technology, such as a relatively high electronic noise and poor stability in aqueous environment have motivated the search for more suitable materials. In this respect, the outstanding electronic and electrochemical performance of graphene holds great potential for bioelectronic applications.
