Abstract
In this work, we performed analytical and numerical studies of a nanowire array field-effect biosensor. The concept of the electrical double layer is applyed in conjunction with a nanowire junctionless FET model. The model accounts for biosensing dynamics, and the sensor's sensitivity is evaluated for femtomolar variations of biomolecule concentration within the analyte solution. The signal-to-noise ratio (SNR) is also estimated, providing a lower bound on the detectable concentration.
