Abstract

Anchored, biotinylated phospholipids forming the capturing layers in an electrolyte‐gated organic field‐effect transistor (EGOFET) allow label‐free electronic specific detection at a concentration level of 10 nM in a high ionic strength solution. The sensing mechanism is based on a clear capacitive effect across the PL layers involving the charges of the target molecules.
