extremely significantP <0.001
The 5 μg/mL dose of 0.05M and 0.01M synthesized ZnO NPs showed extremely significant difference when compared with control ( P <0.001, n≥3, Figure 9B ), but a similar concentration of 0.1M ZnO NPs revealed significant difference upon comparison with the control ( P <0.001, n≥3, Figure 9A ).
