Enzyme‐Responsive Polymer Nanoparticles via Ring‐Opening Metathesis Polymerization‐Induced Self‐Assembly

Photoinduced heterodisulfide metathesis for reagent-free synthesis of polymer nanoparticles.

Reagent-free synthetic methods are of great interest because of their simplicity and implications in green chemistry. We have taken advantage of photoinduced heterodisulfide metathesis to generate crosslinked polymer nanoparticles. The method of development and the mechanistic basis for the synthetic approach are outlined in this communication.

Hollow hybrid polymer-graphene oxide nanoparticles via Pickering miniemulsion polymerization.

The preparation of hybrid hollow capsules consisting of a cross-linked polymer shell and a coating of graphene oxide (GO) is demonstrated. The capsules are prepared by Pickering miniemulsion polymerization, exploiting the surface activity of GO for its use as a colloidal surfactant. This approach represents a simple and convenient route towards hollow carbon nanostructures for a variety of appl...

Thermally reversible self-assembly of nanoparticles via polymer crystallization.

The directed self-assembly of gold nanoparticles through the crystallization of surface-grafted polyethylene oxide (PEO) in ethanol-water mixtures is described. This process is fully reversible and tunable through either the size of the core or the polymeric coating. Characterization by X-ray scattering and electron microscopy of the self-assembled structures reveals order at the nanoscale, typ...
