Web12 jul. 2024 · Toxicity of Ag + ions and AgNPs in bacteria Escherichia coli is among the most studied bacteria regarding silver toxicity. AgNPs were shown to be more effective than Ag + ions in E. coli, by interacting with the inner and outer membranes and releasing Ag + ions locally upon AgNP dissolution. http://eduterre.ens-lyon.fr/ressources/scenario1/planetebleue/tp/tp_salinite_mohr/
