Abstract
A method of producing dendritic gold nanoparticles by combining a gold precursor solution, a reducing agent, and a bifunctional peptide having an amine-rich amino acid sequence into a buffered aqueous solution in a single container, and agitating the mixture causing the formation of the dendritic gold nanoparticles having a surface with a positive charge and a second end portion of the bifunctional peptide exposed on the surface of the dendritic gold nanoparticles. The dendritic gold nanoparticles may be used to deliver therapeutic, diagnostic, and/or immunogenic amino acid sequences as portions of the bifunctional peptide.
