Versions Notes

Error in Figure

In the original publication [1], there were some mistakes in Figures 4 and 5 as published. In Figure 4, the X-axis is corrected, but the label of the X-axis was missing a “/” symbol, The corrected Figure 4 appears below.
In Figure 5 GE-1 cells cytotoxicity test, there was statistical mistake as published. The corrected Figure 5 appears below.

Text Correction

There was an error in the original publication due to the statistical mistake. A correction has been made to Section 3.2. Cytotoxicity. The corrected paragraph appears below.
The toxicity of each compound was tested against GE-1 cells. LDH and CCK8 assays were performed for 24 and 72 h, respectively. Among the six materials, both CE and GP showed a significant difference (p < 0.01) compared to cotton (Figure 5). On day 3, GP showed the highest level of LDH cytotoxicity, indicating toxicity to the GE-1 cells in comparison to cotton. PTFE, PF, and wax showed no signs of cytotoxicity compared to cotton.
As shown in Figure 5B, the CCK8 assay results were consistent with that of the LDH assay. CE and GP showed the lowest cell viability of GE-1 cells, which was significantly lower than that of cotton and the other materials on day 3 (p < 0.01). The GE-1 cell samples were inspected under an Olympus IX70 Microscope with TH4-100 Lamp and DP25 photo image (Olympus, Tokyo, Japan) to observe the qualitative results (Figure 6).
This correction was approved by the Academic Editor. The original publication has also been updated.
