Gold cellular networks inside water-soluble sodium alginate sol
The present work demonstrates the fabrication of unique gold cellular networks inside water-soluble sodium alginate sol. In conjunction with control experiments, UV–vis spectra and TEM images structurally give a piece of robust evidence that Au(III) and sodium alginate combined with preparation parameters synergically favor the formation of gold cellular networks. From the viewpoint of green chemistry, the cheap and safe reactant sodium alginate and the friendly aqueous medium make the present method possible for applications in large-scale production of metallic cellular networks. Thus, coupled with facile and green creation, the gold cellular networks open new opportunities for noble metal nanostructures, with different morphologies, as biological labels, energy transfer pairs, and other nanoscale electronics.
