Clinically, significant challenges remain in the treatment of implant-associated osteomyelitis. Herein, we modified process an active screen plasma surface technique to prepare a silver nanoparticle coating and then performed vitro vivo experiments investigate effectiveness nanoparticle-coated products prepared using this innovative treating Staphylococcus- Pseudomonas aeruginosa-induced Consequently, microstructures, antibacterial properties, corrosion performance, biocompatibility, biosafety materials were evaluated our study. The capacity 2h-Ag-aspsm@SS was investigated microbiological counting assays, bacterial viability biofilm formation observations, expression biofilm, compared antibiotic bone cement nails control groups. Similarly, through micro-CT, cultures, histopathological staining. biocompatibility safety examinations, including blood biochemical tests histology, showed that Ag-aspsm@SS caused no obvious harm body. In summary, study demonstrated could potentially serve as implant for osteomyelitis with long-lasting antimicrobial capacity.

Efficient visible-light-driven photocatalytic removal of Acid Blue 92, E. coli, and S. aureus over Ag-AgCl nanoparticles-decorated bismuth sulfide microparticles

Abstract Bismuth sulfide particles were modified with Ag-AgCl nanoparticles to make a visible light active plasmonic photocatalyst. The powder x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive (EDX), elemental mapping, nitrogen adsorption–desorption isotherms (BET-BJH), photoluminescence (PL), and diffuse reflectance (DRS) techniques served analyze the morphological structural properties. To evaluate photocatalytic performance, Acid Blue 92 (AB92) azo dye was degraded in aqueous solution under irradiation. According results, 0.025 g of photocatalyst able remove more than 98% AB92 at 15 ppm concentration neutral acidity, following pseudo first-order kinetics. Superoxide anion radicals (O 2 •− ) also recognized as most key species promoting photodegradation pathway. Also, antibacterial activity materials explored against E. coli S. aureus pathogenic bacteria irradiation dark conditions. Using transmission (TEM) images treated cells, it found that damaged cell wall structure both gram-positive negative within h significantly, which could be attributed efficient production destructive superoxide on surface Ag-AgCl/Bi S 3 illumination.
