Water-soluble gold nanoparticles

Water-soluble gold nanoparticles (Au NPs) stabilized by a nitrogen-rich PEG-tagged substrate have been prepared by reduction of HAuCl₄ with NaBH₄ in water at room temperature. The morphology and size of the nanoparticles can be controlled by simply varying the gold/stabilizer ratio. The nanoparticle...
