title: Biotinylated glycopolymers synthesized by atom transfer radical polymerization.
abstract: Biotinylated glycopolymers that bind to the protein streptavidin were synthesized by atom transfer radical polymerization (ATRP). Poly(methacrylate)s with pendent N-acetyl-d-glucosamines were prepared by polymerizing the protected monomer, followed by deprotection. Alternatively, the unprotected monomer was directly polymerized. Both paths provided well-defined glycopolymers with narrow molecular weight distributions (PDI = 1.07-1.23). The number-average molecular weights determined by gel permeation chromatography increased with increasing initial monomer-to-initiator ratios. The polymers were synthesized using a biotin-functionalized initiator for ATRP. Confirmation of the end group and binding to the protein streptavidin was achieved by (1)H NMR and surface plamon resonance.
