Abstract

Nanoparticles working together. Thermoresponsive polymer-coated nanoparticles are shown to display size dependent, cooperative, lower critical solution temperature behavior. This was exploited to direct the assembly of appropriate nanoparticles onto complementary polymer brush coated surfaces.
