*4.11. Statistical Analysis*

All data are expressed as mean ± SD of three independent experiments. Statistical tests were performed using IBM SPSS (v21). Briefly, the Kolmogorov–Smirnov test and Levene's test were used to check the normality of the data distribution and the homogeneity of variance of the data, respectively. Then, Student's *t*-test and the Tukey–Kramer test were used for statistical analysis. The asterisk symbol (\*) indicates significant difference at *p* < 0.05.
