Preparation of hydrophobically modified poly(amidoamine) dendrimer-encapsulated gold nanoparticles in organic solvents
HAuCl4 in aqueous solution was extracted to toluene or chloroform using a hydrophobically modified poly(amidoamine) dendrimer. Then, by reduction of Au3+ ions with dimethylamineborane, gold nanoparticles in the size range of 2-4 nm were obtained in toluene or chloroform. It is suggested that gold nanoparticles are encapsulated by the dendrimer,
