Abstrakt: Three kinds of novel facile fabrication routes to prepare Au-F127 nanocolloids with different morphologies including rambutan-like Au-F127 hybrid nanospheres, Au@F127 core-shell nanostructure, and multiple shapes of Au nanosheets are reported. The different Au-F127 nanocolloids are characterised by transmission electron microscopy, electron diffraction patterns, and UV-vis spectroscopy. The different formation mechanisms of the Au-F127 nanocolloids with different morphologies are discussed. The intrinsic properties and application potential of Au-F127 nanocolloids are determined by their size, shape, composition, and structure. A biosensor made of rambutan-like Au-F127 hybrid nanospheres exhibited a good electrocatalytic activity for the reduction of hydrogen peroxide. The Au@F127 core-shell nanoparticles exhibited good blood compatibility attributable to the surface hydrophilicity of the F127 layer. These strategies open up the exciting possibility of using F127 in synthesis of gold nanomaterials of variable morphology, and provide a promising platform for biomedical applications in future.
