ld nanoparticles were covalently attached to the thiol-terminated surface, which was created by aqueous silanization of the single crystal silicon substrate with 3-mercaptopropyl-trimethyl-silane(3-MPTMS). This paper reports the first evidence for Au-S bonding between the ld particles and the surface thiol-groups given by the angle resolved XPS measurements.
