*4.8. Statistical Analysis*

All assays were performed with either three or more repetitive experiments. Student's *t*-test was performed to determine the significant difference, and standard error were calculated using the Built-in Functions in Excel 2016. Student's *t*-test, '\*', '\*\*', and '\*\*\*' indicate significant difference at *p* < 0.05, *p* < 0.01, and *p* < 0.001, respectively.
