“…The X-ray diffractogram (Figure C) results in a prominent peak at approximately 13.5°, which is characteristic of GO. , In the sample GO-Ag1, the peak at 34.2° refers to the silver anchoring . This position can be displaced by the degree of oxidation and hydration of the GO sample and by the relative humidity during the X-ray diffraction measurements .…”

“…Similar bands appear in the Raman spectra of GO-Ag1 (D band at 1347.68 cm –1 , G band at 1590.18 cm –1 ) and GO-Ag2 (D and G bands at 1354.82 and 1577.84 cm –1 , respectively) (Figure B). The peaks at ∼248 cm –1 and ∼922 cm –1 indicate the Ag–O bond at the spectrum of GO-Ag1 (Figure B). Aside from the D and G bands, the GO-Ag2 spectrum displays additional peaks at approximately 459 and 979 cm –1 , indicating the presence of a Ag–O bond, which is absent in the GO sample.…”

This study reports on the modification of bacterial cellulose (BC) membranes produced by static fermentation of Komagataeibacter xylinus bacterial strains with graphene oxide-silver nanoparticles (GO-Ag) to yield skin wound dressings with improved antibacterial properties. The GO-Ag sheets were synthesized through chemical reduction with sodium citrate and were utilized to functionalize the BC membranes (BC/GO-Ag). The BC/GO-Ag composites were characterized to determine their surface charge, morphology, exudate absorption, antimicrobial activity, and cytotoxicity by using fibroblast cells. The antimicrobial activity of the wound dressings was assessed against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. The results indicate that the BC/GO-Ag dressings can inhibit ∼70% of E. coli cells. Our findings also revealed that the porous BC/GO-Ag antimicrobial dressings can efficiently retain 94% of exudate absorption after exposure to simulated body fluid (SBF) for 24 h. These results suggest that the dressings could absorb excess exudate from the wound during clinical application, maintaining adequate moisture, and promoting the proliferation of epithelial cells. The BC/GO-Ag hybrid materials exhibited excellent mechanical flexibility and low cytotoxicity to fibroblast cells, making excellent wound dressings able to control bacterial infectious processes and promote the fast healing of dermal lesions.
