  • Process for producing gold nanoparticles
    Patent number: 7232474
    Abstract: Gold nanoparticles having a particle size of 4-15 nM are synthesized by the reduction of hydrogen tetrachloroaurate (III) trihydrate using a suitable reducing agent such as sodium citrate in the presence of unmodified ?, ? or ?-cyclodextrin. The particle size is dependent upon the type and concentration of cyclodextrin and the reducing agent concentration. Gold nanoparticles having a particle size of 2-4 nM are produced by the reduction of hydrogen tetrachloroaurate (III) trihydrate using sodium borohydride in the presence of cyclodextrins.
    Type: Grant
    Filed: July 9, 2004
    Date of Patent: June 19, 2007
    Assignee: National Research Council of Canada
