*4.11. Statistical Analysis*

All experiments were repeated at least 3 times, and the data were presented as the mean ± standard deviation (SD). Statistical di fferences were analyzed using a one-way analysis of variance (ANOVA). A threshold *p*-value of 0.05 or 0.01 indicated a significant di fference.
