(a) UV-Vis extinction spectroscopy with the effect of pH on synthesis of SNPs. A. pH 9, B: pH 11, C: pH 7, D: control, E: pH 5, and F: pH 3. Spectra A: pH 9 and B: pH 11, show maximum synthesis of SNPs with symmetry in graph. (Figure 5(b) inset) Zeta potential values of SNPs synthesized at different pH (range of acid to alkali): pH 11, maximum zeta potential value is responsible for the stability of SNPs. Monodispersity ((c) inset): particle size distribution by NTA of pH 11.
