This is the first research that investigated the antibacterial activity of chitosan produced from the three Gold nanoparticles (AuNPs) capped with chitosan (CS-AuNPs), glycol-chitosan (GC AuNPs) and poly-γ-glutamic acid (PA-AuNPs) were applied on fabrics and evaluated for antibacterial activity. In previous studies, greater antibacterial activity was more evident against G − bacteria than G + bacteria, whereas in some studies G + bacteria were more sensitive The broad-spectrum antimicrobial activity of chitosan offers great commercial potential for this product. Nevertheless, the antimicrobial activity of chitosan varies, because this activity is associated with its physicochemical characteristics and depends on the type of microorganism Nanocellulose (NCC) and chitosan (CS) films The antibacterial activity of the extracted chitosan against Klebsiella pneumonia, Staphylococcus aureus, and Shigella dysenteriae was notably higher at μg/mL concentration (6, 5, andmm, respectively), which did not increase further with high chitosan concentrations. Overall, and μg/mL concentrations of the chitosan Given chitosan’s antimicrobial and immunological properties, we investigated whether chitosan-alginate NPs could be effectively generated, stored, and delivered in physiologic parameters,demonstrate antimicrobial and anti-inflammatory activity against a clinically important cutaneous bacterium, P. acnes, and whether these NPs might be aShows antibacterial activity: S. aureus: Chitosan/Ciprofloxacin: Hydrogel: Inhibits bacterial growth: E. coli: Chitosan/Clindamycin: Hydrogel: Enhances the antibacterial properties: E. faecalis: Chitosan/Ciprofloxacin Fluconazole: Hydrogel(Bandage) Shows significant antimicrobial activity: C. albicans E. coli S. aureus: Chitosan/Minocycline Recently, studies showed that chitosan has intrinsic antimicrobial activity. PA-AuNPs showed a higher antibacterial activity against S. enterica and E. coli -OH7 compared to gentamycin The mechanism of antibacterial action is an intricate process that varies between G − and G + bacteria as a result of the differences in cell wall and cell membrane chemistry. The formed CNPs produced antibacterial activity against all tested strains, including those resistant to multiple antibiotics, with a minimum inhibitory concentration (MIC) of Hydrogel COA-T3 composed of quaternized chitosan (QCS) and oxidized dextran (OD) was constructed for co-delivery of the photosensitizer TPI-PN and the antimicrobial peptide 1 day ago · Fresh mulberry is a soft and juicy fruit with no protective layer on the skin, limiting its storage and transportation.
