“…The industrial technical samples of Na-CMC (C 6 H 12 O 6 ) with a degree of substitution (DS) of 0.95 and a degree of polymerization (DP) of 900 were purchased from "Promxim Impex" Ltd. (Uzbekistan) and were used after purification from accompanying inorganic and organic impurities. The industrial technical samples of Na-CMC with DS of 0.95 and DP 900 were purified and separated soluble fraction by method 31 After purification and separation was obtained Na-CMC with a DS of 0.97 and a DP of 850. Purified and separated of soluble fraction samples of Na-CMC 32 with a DS of 0.97 and a DP of 850 were used as polymer matrices.…”

Stable silver nanoparticles were synthesized in solutions containing sodium‐carboxymethylcellulose and polyvinyl alcohol, and their structure, morphology, and physicochemical properties were studied. The morphology and diameter sizes of the nanofibers of carboxymethylcellulose/polyvinyl alcohol containing silver nanoparticles were investigated using atomic force microscopy and scanning electron microscopy. The investigations showed that nanofibers with diameter sizes ranging from 50 to 130 nm were obtained from the carboxymethylcellulose/polyvinyl alcohol/silver nanoparticles solution. The size and form of silver nanoparticles formed within the solution of carboxymethylcellulose/polyvinyl alcohol based on nanofiber were determined by X‐ray diffraction (XRD), UV–visible (UV–VIS) spectroscopy, and dynamic light scattering (DLS) investigations, revealing nanoparticles with diameters ranging from 5 to 26 nm. The nanofiber mat containing silver nanoparticles exhibited significant antimicrobial activity against both Staphylococcus epidermidis and Candida albicans. The nanofiber mat containing stable silver nanoparticles could be utilized as an antimicrobial facemask for air filtration and for the treatment of burn wounds.

“…[5][6][7][8][9][10] A film of a biodegradable polymer which is soluble in water is known as sodium carboxymethylcellulose (Na-CMC). Purified Na-CMC 11 is widely used in pharmaceuticals and medical practices due to its adhesiveness, biodegradability, biosolubility, and nontoxicity, as well as forming gels, suspensions, microneedles, nanofibers, and films and possessing sorption and stabilizing properties, making it suitable for drug delivery and active substances in the treatment of burn wounds, cancer and hemostatic pharmaceutical devices. [12][13][14][15][16] Different concentrations of Na-CMC solutions perform a stabilizing function in the synthesis of metal nanoparticles and nanorods, and carboxymethyl groups are allowed to control their sizes and shapes during synthesis.…”

In this study, selenium nanoparticles (SeNPs) were synthesized and stabilized by reducing sodium selenite using ascorbic acid in an aqueous solution of sodium carboxymethylcellulose (Na‐CMC) with a degree of substitution of 0.97 and a degree of polymerization of 810. IR‐Fourier spectroscopy revealed that coordination bonds between functional groups in Na‐CMC and SeNPs resulted in the development of polymer‐metal complexes. UV–Vis spectroscopy, scanning electron microscopy (SEM), atomic force microscopy (AFM), and dynamic light scattering (DLS) methods were used to determine the SeNP sizes in the structure of the nanocomposite film. Investigation of the stabilization and nonstabilization of SeNPs over several cycles has shown that the effect of the polymer matrix of Na‐CMC on the stabilization of nanoparticles was achieved for 672 h, which was confirmed by the unchanged size distribution and resistance to change of the SeNPs synthesized in Na‐CMC solutions.
