摘要：

We have demonstrated a facile infiltration process, in which gold nanoparticles are assembled into block copolymer brushes. After solvent annealing, the polymer-covered nanoparticles are either sequestered into the corresponding block copolymer domain or expulsed from the brush, depending on the shell density of the nanoparticles.
