| Abstract: | The anti-viral efficacy of face mask was enhanced by applying the protein lactoferrin, the polyphenol catechin individually, and in combination. Individual solutions of protein and polyphenol were meticulously prepared and subsequently sprayed onto the inner surface of face mask layers composed of polypropylene. The functionalized mask layers were subjected to comprehensive characterization through Fourier transform infrared spectroscopy, zeta-potential measurements, and X-ray photoelectron spectroscopy. Goniometry was employed to assess the wettability of the modified surface layer, and air permeability was quantified both before and after the application of potential anti-viral agents. Bioactivity, such as anti-oxidant activity using ABTS assay and anti-viral efficiency against the model virus phi6, was followed as well. Our findings indicate the successful modification of mask with lactoferrin, while functionalization by catechin proved to be unsuccessful. The measured contact angles underscored the hydrophobic nature of the functionalized samples, ensuring reduced wettability in the presence of saliva droplets. Notably, the individual coating layers exhibited enhanced anti-oxidant activity and demonstrated anti-viral properties against the model virus phi6, when the outer layer of the mask was spray-coated. These results suggest promising technology to integrating these functionalized layers into masks for enhanced safety performance. |
