Gold nanoparticle‐modified capacitive field‐effect sensors: Studying the surface density of nanoparticles and coupling of charged polyelectrolyte macromolecules

Abstract The coupling of ligand‐stabilized gold nanoparticles with field‐effect devices offers new possibilities for label‐free biosensing. In this work, we study the immobilization of aminooctanethiol‐stabilized gold nanoparticles (AuAOTs) on the silicon dioxide surface of a capacitive field‐effect...
