摘要：

We synthesized nanostructured AgNbO3silver perovskiteoxide, which prevents the proliferation of microbial cells without undergoingcorrosion. The compound was tested for antimicrobial activity against Gram-positiveStaphylococcus aureusand Gram-negativePseudomonas aeruginosa.We confirmed that the antimicrobial activity of the compound was notrelated to its high dielectric and piezoelectric properties. While the measuredactivity, as quantified by the minimum inhibitory concentration, was similarto the activity of Ag2O particles subjected to the same mechanical treatments,the level of silver ion release of Ag2O was 60 times higher than that ofAgNbO3. This indicated that the antimicrobial activity of AgNbO3is not dueto corrosion resulting in silver ion release to the media.
