The design of bioelectronic devices that enables accurate detection of biomolecules in ionic solutions at physiologically-relevant concentrations remains a challenge. Here, the authors report a ion-impermeable supported lipid bilayer-assisted field-effect transistor platform for biomolecule detection.
