Confocal scanning laser microscopy images of bacterial cells (A) S. aureus; (B) S. aureus exposed to complexed PenG on monolayer carboxylic acid coated sNPs; (C) S. aureus exposed to complexed PenG on carboxylated polymer grafted sNPs; (D) S. aureus exposed to free PenG (Scale bars: 50 µm). The Pn–nanoparticles complexes (B and C) have equal doses of PenG as the free PenG group (D).
