Here, we present a protocol to study cellular adhesion using field-effect transistor (FET) devices. This is a label-free and real-time electronic platform complementing the established Electrical Cell-substrate Impedance Sensing (ECIS) method for measurements of adhesion and detachment of confluent cell cultures and is pushing spatial resolution down to single cell.
