A facile approach to prepare hybrid nanoparticles with morphology controlled by the thickness of glyco-shell

摘要

Herein, we designed a novel amphiphilic triblock glycopolymer poly(oligo(ethyleneglycol) methacrylate)-block-poly(maltopyranoside methacrylate)-block-polystyrene(POMA-b-PMal-b-PS) via the combination of reversible addition-fragmentation chain transfer(RAFT) polymerization and postpolymerization 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 Au NPs. By controlling the thickness of glyco-shell, we successfully obtained Janus particles and raspberry-like particles with Au NPs in the sugar shell.
