Preparation and characterization of Fe–ZnO cellulose-based nanofiber mats with self-sterilizing photocatalytic activity to enhance antibacterial applications under visible light

RSC Advances, Journal Year: 2024, Volume and Issue: 14(26), P. 18536 - 18552

Published: Jan. 1, 2024

Bacterial infections and antibiotic resistance have posed a severe threat to public health in recent years. One emerging promising approach this issue is the photocatalytic sterilization of nanohybrids. By utilizing ZnO sterilization, drawbacks conventional antibacterial treatments can be efficiently addressed. This study examines enhanced sterilizing effectiveness Fe-doped nanoparticles (Fe-ZnO nanohybrids) incorporated into polymer membranes that are active visible light. Using co-precipitation procedure, Fe-ZnO nanohybrids (Fe

Published: Jan. 16, 2025

Biomimetic patterning emerges as a promising antibiotic-free approach to protect medical devices from bacterial adhesion and biofilm formation. The main advantage of this lies in its simplicity scalability for industrial applications. In study, we employ it produce antibacterial coatings based on silicone materials, widely used the healthcare industry. doing so, patterned substrates with topography various flower petals (rose, chamomile, pansy, magnolia) studied relationship between properties obtained biomimetic their surface topography. To study surfaces, fractal analysis SEM images. particular, measure complexity heterogeneity, values developed interfacial area ratio (Sdr) lacunarity coefficient (β). result, found that coverage decreased exponentially increase prominent were observed at β > 1.6 Sdr 50. results can be identify materials superior efficient biomedical

Antibacterial activity of extracellular biosynthesized iron oxide nanoparticles against locally isolated β-lactamase-producing Escherichia coli from Egypt

Deleted Journal, Journal Year: 2024, Volume and Issue: 6(3)

Published: March 8, 2024

Abstract Nowadays, extended spectrum β-lactamase (ESBL) producing Escherichia coli has been recognized and recorded worldwide as one of the main causing agents a major contributor to nosocomial infections. The current study aimed isolate detect β-lactamase-producing E. use it in extracellular biosynthesis iron oxide nanoparticles (Fe 2 O 3 NPs). Fifteen Gram-negative (G-ve), lactose-fermenting, negative citrate non-spore-forming coliform bacteria were isolated from total bacterial isolates water samples. Different tests performed including chromogenic methods acidimetric iodometric techniques phenotypic cloverleaf test Masuda double-disc test. ESBL-producing was detected confirmed by modified double disc synergy using ceftazidime, cefotaxime, ceftriaxone, amoxicillin combined with clavulanic acid, imipenem, cefepime, cefoxitin. quantitative assay done micro-iodometric assay. Among isolates, S1B1 (the highest activity) selected tested for Fe NPs. produced (NPs) characterized UV–visible spectroscopy, X-ray diffraction analysis, Fourier-transform infrared spectroscopy (FTIR), transmission electron microscope Zeta analysis. Results successful NPs which displayed an absorption peak at 346 nm crystallographic lattice plane (104). negatively charged spherical-shaped average size ≈ 24 ± nm. FTIR refers presence NPs-associated proteins act stabilizing capping agents. Antibacterial activity against Staphylococcus aureus ATCC25923, Bacillus cereus ATCC6633 (G+ve bacterium), Pseudomonas aeruginosa ATCC27853 (G-ve well strain. revealed moderate strong antibacterial action strains minimum inhibition concentration (MIC) ranging 25 40 µg/ml.
