TABLE 1.

Physicochemical properties of NPs obtained by UV-Vis, SAXS, and ζ -potential measurements. The reported concentration values correspond to the concentration of NPs in the aqueous dispersion, obtained from the synthesis. Before each measurement, AgNPs concentration has been adjusted by dilution, to match the one of AuNPs (8.3 × 10⁻¹⁰ M).

	Conc.(M)	λmax (nm)	Size (nm)	ζ-pot.(mV)
AuNPs	8.3 × 10−10	519	20 ± 1	−22.5 ± 1
AgNPs	1.8 × 10−8	406	22 ± 1	−18.9 ± 0.3
