Variables measured to establish the stability of the manufactured AgNP stock solutions
over time: pH, surface plasmon resonance band (SPRB), width of the SPRB at half height
(Wh/2), ζ-potential (ζ), hydrodynamic diameter (dh), diameter (TEM), total silver (Agtotal)
and free silver ions and its complexes (Ag+). The standard deviations of at least two different
measurements are shown between parentheses.
