Abstract

ABSTRACT Poly (ethylene glycol)(PEG) is often used to biocompatibilize surfaces of implantable biomedical devices. Here, block copolymers consisting of PEG and l-cysteine- containing poly (amino acid) s (PAA's) were synthesized as polymeric multianchor systems for the covalent attachment to gold surfaces or surfaces decorated with gold nanoparticles. Amino-terminated PEG was used as macroinitiator in the ring-opening polymerization,( ...
