摘　　要：Herein, we designed a novel amphiphilic triblock glycopolymer poly（oligo（ethyleneglycol） methacry- late）-block-poly（maltopyranoside methacrylate）-block-polystyrene （POMA-b-PMal-b-PS） via the com- bination of reversible addition-fragmentation chain transfer （RAFT） polymerization and post- polymerization modification. The micelles with core-shell-corona structures were prepared by direct self-assembly of this glycopolymer in water. We found that these micelles can be used in in situ formation and stabilization of AuNPs. By controlling the thickness of glyco-shell, we successfully obtained lanus particles and raspberry-like particles with AuNPs in the sugar shell.Herein, we designed a novel amphiphilic triblock glycopolymer poly（oligo（ethyleneglycol） methacry- late）-block-poly（maltopyranoside methacrylate）-block-polystyrene （POMA-b-PMal-b-PS） via the com- bination of reversible addition-fragmentation chain transfer （RAFT） polymerization and post- polymerization modification.
