  Seamless connection of molecular nanonetworks to macroscale cyber networks is
envisioned to enable the Internet of Bio-NanoThings, which promises for
cutting-edge applications, especially in the medical domain. The connection
requires the development of an interface between the biochemical domain of
molecular nanonetworks and the electrical domain of conventional
electromagnetic networks. To this aim, in this paper, we propose to exploit
field effect transistor based biosensors (bioFETs) to devise a molecular
antenna capable of transducing molecular messages into electrical signals. In
particular, focusing on the use of SiNW FET-based biosensors as molecular
antennas, we develop deterministic and noise models for the antenna operation
to provide a theoretical framework for the optimization of the device from
communication perspective. We numerically evaluate the performance of the
antenna in terms of the Signal-to-Noise Ratio (SNR) at the electrical output.
