Sonochemical synthesis of gold nanoparticles on chitosan

Sonochemical synthesis of gold nanoparticles on chitosan

Au nanoparticles deposited on chitosan were readily prepared from aqueous solution of NaAuCl 4 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, alth...

Beschreibung
Zusammenfassung:Au nanoparticles deposited on chitosan were readily prepared from aqueous solution of NaAuCl 4 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.
