Histogram of cell count versus propidium iodide (PI) uptake. A corresponds to the untreated MRSA (live cells); B, C and D indicate the proportion of dead MRSA cells following incubation with bare VCM at its MIC (7.8 μg/mL), bare VCM in NPs MIC (3.9 μg/mL) and VCM-HNLCs at its MIC (3.9 μg/mL), respectively. The experiment was conducted in triplicate (n = 3)
