Abstract

Au nanoparticles deposited on chitosan were readily prepared from aqueous solution of NaAuCl4 containing chitosan powder by the reaction with sonochemically formed reducing species. The average size of the formed Au particles was measured to be 22 nm with a relatively narrow size distribution, although there was no specific stabilizer for Au nanoparticles.
