In situ fabrication of flower-like gold nanoparticles in surfactant-polyoxometalate-hybrid spherical assemblies

Flower-like gold nanoparticles (Au-NPs) were fabricated in surfactant-PMo12 hybrid assemblies, where PMo12 served as a UV-switchable reducing agent for producing Au-NPs and the organic surfactant matrices played the role of a soft template for the formation of flower-like structure of Au-NPs.
