Abstract
The present invention is directed to a method for fabricating a gold nanoparticle, the method comprising the steps of contacting a gold ion with a protein, wherein the protein has an inner cavity that can accommodate the gold ion, separating the protein with the encapsulated gold ion(s) from non-encapsulated gold ions, contacting the protein-encapsulated gold ion with a first reductant to reduce the gold ion and form a gold nanocluster seed in the inner cavity of the protein, wherein the first reductant is a strong reductant, and contacting the gold nanocluster seed in the inner cavity of the protein with a second reductant to mineralize and grow the gold nanoparticle.
