No chemicals are used in the generation of gold nanoparticles, except gold salts
While gold salts
dominated the treatment of rheumatoid arthritis in the last one hundred years, it was through statistical analysis that methotrexate was found to be superior and gold salts
nearly abandoned in the last decade.
Robert Dickson and his colleague of the Georgia Institute of Technology in Atlanta created the clusters by dissolving gold salts
in a solution containing branched-polymer molecules called dendrimers.
Colloidal gold is a solution of gold nanoparticles that is manufactured from inexpensive gold salts
Although no longer widely available, when used gold salts
can cause myopathic symptoms.
