Antimicrobial Properties of Polyester/Copper Nanocomposites by Melt-Spinning and Melt-Blowing Techniques

Published: Nov. 6, 2023

With the growing demand for personal protective equipment (PPE) in face of pandemic events caused by SARS-COV-2, opportunity arises development materials with characteristics such as antimicrobial, antiviral, antifungal activity, etc. The use polymeric nanocomposites based on polyester/copper offers an alternative great interest due to versatility raw material and high efficiency copper antimicrobial additive. In this study, textile fibers prototypes different Cu nanoparticles (CuNP) content were produced using melt-spinning obtain bi-component multifilament fibers, melt-blowing non-woven fabrics. tested against pathogenic microorganisms S. aureus, E. coli, C. albicans. It was shown that offer more excellent protection pathogens, while fabric only shows activity coli. possible identify CuNP confined exclusively outer cover analytical techniques, which may be associated increase compared present fabric, even when they same content.

Biosynthesis of Chitosan Nanocomposite with Myrrh-Mediated Nanosilver for Controlling Skin Pathogenic Microbes

Natural Product Communications, Journal Year: 2024, Volume and Issue: 19(11)

Published: Nov. 1, 2024

Background: The usages of biosynthesized nanomaterials for microbial pathogens’ fighting have numerous rationales and effectiveness. Skin microbes could acquire drug-resistance that needs innovative approaches overcoming. Objectives: Phytosynthesized silver nanoparticles (AgNPs) with Commiphora myrrh resin extract (MR) their nanoconjugates chitosan (Cht) were fabricated assessed as potential antimicrobial agents controlling antibiotic-resistant skin pathogens, Materials methods: AgNPs biosynthesis was achieved within MR solution they composited Cht. syntheses validated using infrared spectroscopy electron microscopy loaded onto cotton textiles, then all nanomaterials/textiles inhibiting pathogens Staphylococcus aureus Candida albicans. Results: Nanomaterials’ characterization appointed the mean size MR-synthesized to be 22.58 nm, whereas diameter Cht/MR/AgNPs nanocomposites 130.34 nm carry +25.9 mV charges. assessment interactions between employed materials. textiles MR/AgNPs effectively inhibit growth albicans, most powerful. scanning confirmed action toward pathogens; mostly lysed deformed 12 h exposure nanocomposites. Conclusions: nanocomposite provided potent actions pathogens.
