(A) Cell morphology of RAW264.7 macrophages after treatment with different concentrations of AiiA AuNPs for 24 h. Cells grown with medium, AiiA protein, and AuCl4 were used as controls. (B) Cytotoxic activity of AiiA AuNPs on RAW264.7 mouse macrophages. Macrophages were treated with different concentrations of AiiA AuNPs for 24 h. Macrophages treated with AiiA protein and AuCl4 were used as controls. Cells viability was determined by MTT assay. Experiments were performed in triplicates; means ± SDs are shown.
