Amphiphilic block copolymers composed of polyacrylamide (PAAm) bearing maltose (Mal) moieties, poly(N-tert-butylacrylamide) (PTBAAm) segments, and a terminal acryloyl group were synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization and thiol-ene reaction. The resulting glycopolymer-type macromonomers were used to prepare Mal-decorated polymer particles by dispersion copoly-merization of the Mal-bearing block copolymers with styrene. The carbohydrate-decorated polymer particles in aqueous suspension were specifically recognized by the lectin Concanavalin A (Con A).
