Fig. 7From: New formula of the green synthesised Au@Ag core@shell nanoparticles using propolis extract presented high antibacterial and anticancer activityA heatmap and SEM images for the bacteria damage after adding the Au@AgNPs. The heat map of A P. aeruginosa B S. sciuri C S. enterica. The SEM images for the bacterial damage in the cell membrane of D, G P. aeruginosa, E, H S. sciuri, and F, I S. enterica after exposure to the Au@AgNPs in the concentrations marked in the black box (A–C).
