摘要：
Reversibly-photoswitchable gold nanoparticles containing azobenzene and exhibiting a light response "virtually identical'' to that of the free chromophore were achieved by self-assembling a host-guest inclusion complex between alpha-cyclodextrin and an azobenzene-terminated alkanethiol in an aqueous medium.
