In the ElectroMed project, we are interested in screening certain peptide sequences for their ability to selectively interact with antibodies or MHC proteins.This poses a combinatorial challenge that requires a highly multiplexed setup of label-free immunosensors.Label-free FET-based immunosensors are good candidates due to their high multiplexing capability and fast response time.Nanowire-based FET sensors have shown high sensitivity but are unreliable for clinical applications due to drift and gate stability issues.To address this, a label-free immuno-FET architecture based on planar junctionless FET devices is proposed.This geometry can improve the signal-to-noise ratio due to its larger planar structure, which is less prone to defects that cause noise and is better suited to the functionalization of different receptor molecules.
