Dynamic light scattering (DLS) analysis of MMNPs. (a) Mean hydrodynamic diameters and (b) polydispersity indices (PDI) of multiple batches of MMNPs prepared at various. dopamine·HCl (DA) concentrations and NaOH:DA ratios. n = 3–19 independantly prepared batches of MMNPs were analyzed for each synthetic condition. Error bars represent standard deviations. Bars not sharing symbols in (a) differ significantly with p < 0.001.
