Studies on the dependence of polymeric Au(I)SG precursor size on pH. A. Hydrodynamic radius at different pH values of the polymeric Au(I)SG precursors measured using DLS. Error bars are standard deviation of three trials. B. The size exclusion chromatograms of the polymeric Au(I)SG precursors at pH 4.8, 6.4, and 7.9 with retention times of 22.9, 23.4, and 23.7 min, respectively. The precursors were separated using Superose 6 column with 10 mM phosphate or acetate buffered saline as the elution buffer.
