The average hydrodynamic diameter (d_h) and zeta potential (ζ) of silver nanoparticles (AgNPs), stabilized with sodium bis(2-ethylhexyl) sulfosuccinate (AOT-AgNPs), poly(vinylpyrrolidone) (PVP-AgNPs), and citrate (cit-AgNPs) suspended in anionic reactant solution (c(Na₂HPO₄) = 8 × 10⁻³ mol dm⁻³, γ (AgNPs) = 20 mg dm⁻³, pH 7.4) in the presence or absence of bovine serum albumin (BSA, γ = 200 mg dm⁻³) and chitosan (Chi, γ = 50 mg dm⁻³) at 25 °C.
