“…Precision) were 8.1907 and 7.6546, respectively. These suggested that both models had a high degree of fit and reliability, and the regression results were good [ 31 , 32 ]. In addition, the experimental values of these two models for Y 1 of E. coli and Y 2 of S. aureus were evenly and closely distributed on both sides of the predicted fitting line ( Figure 4 ), indicating the high fit and accuracy of the experimental values.…”

ZnO nanorod nonwoven fabrics (ZNRN) were developed through hydrothermal synthesis to facilitate the prevention of the transmission of respiratory pathogens. The superhydrophobicity and antibacterial properties of ZNRN were improved through the response surface methodology. The synthesized material exhibited significant water repellency, indicated by a water contact angle of 163.9°, and thus demonstrated antibacterial rates of 91.8% for Escherichia coli (E. coli) and 79.75% for Staphylococcus aureus (S. aureus). This indicated that E. coli with thinner peptidoglycan may be more easily killed than S. aureus. This study identified significant effects of synthesis conditions on the antibacterial effectiveness, with comprehensive multivariate analyses elucidating the underlying correlations. In addition, the ZnO nanorod structure of ZNRN was characterized through SEM and XRD analyses. It endows the properties of superhydrophobicity (thus preventing bacteria from adhering to the ZNRN surface) and antibacterial capacity (thus damaging cells through the puncturing of these nanorods). Consequently, the alignment of two such features is desired to help support the development of personal protective equipment, which assists in avoiding the spread of respiratory infections.

“…Its substantial CEC and interlayer domains afford a favorable opportunity for antibacterial agent loading, rendering it an ideal carrier material for antibacterial agents. 16−18 In addition, extant studies have shown that inorganic antibacterial agent/MMT antibacterial materials have a significantly better antibacterial effect on Gram-negative bacteria than Gram-positive bacteria, 19,20 while organic antibacterial agent/MMT antibacterial materials have the opposite antibacterial preference. 21−24 Based on the advantageous carrier properties and the singleloading antibacterial inclination of MMT, we embarked on the following endeavors.…”

By intercalating montmorillonite (MMT) with Cu 2+ and benzalkonium chloride (BAC), the present work constructed a synergistic promotion system (Cu 2+ /BAC/MMT). MMT not only enhances the thermal stability of Cu 2+ and BAC but also facilitates the controlled release of Cu 2+ and BAC. Concurrently, the introduction of BAC improves the material's organic compatibility. In vitro assays show that the "MIC+" of Cu 2+ /BAC/MMT against Staphylococcus aureus is merely 7.32 mg/L and 55.56 mg/L against Escherichia coli. At concentrations of 10 and 25 mg/L, Cu 2+ /BAC/MMT inactivates 100% of S. aureus and E. coli within 2 h, respectively. Furthermore, it is confirmed that the prepared Cu 2+ /BAC/MMT exhibits a long-term antibacterial ability through antibacterial experiments and release tests. Also, the biosafety of this material was also substantiated by in vitro cytotoxicity tests. These comprehensive findings indisputably portend that Cu 2+ /BAC/MMT holds promise to supplant antibiotics as an efficacious treatment modality for bacterial infections.
