Abstract

Oligo(ethylene glycol) terminated molecules were adsorbed on gold. A repulsion with hydrophobically functionalized probes under electrolyte solution was observed. This repulsive force depends strongly on the ion concentration indicating an electrostatic origin. Short chain oligomers with 3-8 EG units adsorbed on gold carry some effective surface charge, while this vanishes for a chain with 45 units.
