Fabrication of Photoactive Electrospun Cellulose Acetate Nanofibers for Antibacterial Applications

The aim of the study was to investigate process electrostatic fabrication cellulose acetate (CA) nanofibers containing methylene blue (MB) as a photosensitizer. electrical, physicochemical, and biocidal properties prepared material were given. CA by electrospinning method using solvent mixture acetone distilled water (9:1 vv?1) different concentrations (i.e., 10–21%). Additionally, implemented into polymer solution with concentration 17% obtain fibers photo-bactericidal properties. Pure electrospun more uniform than MB ribbon shape). Fiber diameters did not exceed 900 nm for tested solutions flow rate below 1.0 mL h?1. concentration, resistivity) other parameters rate, an applied voltage) strongly influenced size fibers. Plasma treatment resulted in reduced biofilm formation on their surface. results activity up 180 min) confirmed high efficiency inactivation Staphylococcus aureus cells without plasma treatment). most effective reduction number equal 99.99 ± 0.3%.
