“…At the same time, the maximum correlation r = −0.41 has been demonstrated between the NP toxicity to yeast cells, log 10 (MIC), and the hydrogen peroxide oxidation rate constant k' of silver NPs, hydrogen peroxide being the biologically significant oxidizer. It correlates well with the findings of the studies [55,67] on the biological activity of silver NP dispersions being dependent on the Ag + ion concentration and on the rate of Ag + ion generation during the oxidative dissolution of NPs.…”

“…In particular, this may be due to the different efficacy of cell membrane binding for particles of various sizes. Moreover, the biological action of silver NPs, as shown in our previous work [55], depends on the NP dissolution speed followed by the release of much more active silver ions. Conversely, the dissolution speed is different for large and small particles and it depends on the particle surface area.…”
