However, a cryogenic process on aqueous gold nanoparticle solution containing tannic acid did not lead to nanoparticle aggregation. The tannic acid serves as surfactant to prevent aggregation of gold nanoparticles. In contrast, a reduction in the particle size in this solution containing tannic acid was observed upon the cryogenic treatment with good reproducibility and uniformity. © 2004 Elsevier B.V.
