The presence of citrated gold nanoparticle (GNP) seeds in aqueous precursor solutions containing L31(8 mM)/F68(4 mM) mixtures reduces the formed GNP sizes, when ≈ 1 mM Au(III) is added, followed by incubation for 7 days at room temperature. (A) Mean hydrodynamic diameters of the formed GNPs against seed concentrations. Data represent the smaller (closed squares) and the larger (open squares) GNPs size populations. Panels (B)-(D) are representative electron micrographs of the larger size population GNPs produced at seed concentrations of (B) 0, (C) 5 (168 ± 123 nm), and (D) 50 pM (110 ± 41 nm).
