Mild-Temperature Synthesis of Gold Colloids with Unique Features Mediated by Polymers of Biomedical Interest.

Early studies carried out in our laboratories , and elsewhere established that AuNP formation at room temperature was dependent on the aqueous dissociation equilibrium involving amino groups and the Au­(III) speciation, pointing that amino groups would have to remain unprotonated to a quite significant degree with a minimum [N]/[Au] ratio required to obtain well-defined particles.
