Inhibition of Na⁺/K⁺-ATPase activity by AgNO₃ and AgNP. The concentration of Na⁺/K⁺-ATPase was 0.5 U/mL (19.5 µg/mL) in all experiments; the concentration of AgNO₃ was selected based on the concentration of dissolved silver in AgNP suspension. Both a silver ion as well as a particle-specific effect was found with the latter being more dominant. Figure was reproduced from Yue et al. [28] with permission from the Royal Society of Chemistry.
