Abstract

original image

Not just a pretty structure: Water-dispersible hybrid nanotubes were used as a desymmetrization tool to prepare Janus nanoparticles consisting of a hydrophobic sphere with water-soluble polymer chains grafted on one side (see picture). The Janus micelles undergo self-assembly to form supermicelles with a flowerlike morphology in which the constituent Janus particles are the “petals”.
