*2.7. Statistics*

Measured data were subjected to statistical analysis. For any given experiment, each data point represented the mean ± standard deviation (SD) of six individual experiments. The Tukey-test was used to determine significance between groups in the contact angle and surface roughness. Statistical significance was indicated by \* *p* < 0.05, \*\* *p* < 0.01, and \*\*\* *p* < 0.001.
