Comparative analysis of DLS and TEM for size characterization, using citrate-stabilized Au nanoparticles prepared with variations in reaction conditions. In each case, multiple measurements were obtained to establish method accuracy. (A) Na-citrate added to aqueous solution of HAuCl4 at reflux; (B) Na-citrate and HAuCl4 mixed at room temperature, then heated to reflux; (C) HAuCl4 added to Na-citrate solution at reflux; (D) Na-citrate and HAuCl4 added to water at reflux. Note that error bars represent standard deviation of multiple measurements, not size dispersity.
