“…Increasing of the silver nitrate concentration in the Na‐CMC structure up to 2.5 wt.% induces the growth of the number of AgNPs sized from 5 to 35 nm and formation of rod‐shaped AgNPs 30 with lengths 50‐140 nm and widths 15‐45 nm (Figure 3C). Thus, increasing of the Ag + content in Na‐CMC films leads to formation of relatively narrow size distribution of spherical and rod‐shaped AgNPs.…”

Silver nanoparticles (AgNPs) stabilized by sodium carboxymethylcellulose (Na‐CMC) with degree of substitution (DS) 0.65‐0.90 and degree of polymerization (DP) 200‐600 were synthesized by photochemical method. The structural, physico‐chemical, and physico‐mechanical properties as well as antimicrobial activity of polymer films containing the Na‐CMC and AgNPs were studied. The shape, quantity, and size of the AgNPs embedded into the Na‐CMC films were determined by UV‐Vis spectroscopy, ZETASIZER Nano ZS, atomic force microscopy and transmission electron microscopy. It was found that the increase of silver nitrate concentration in solution of Na‐CMC followed by photoirradiation leads to the change of size and shape of AgNPs. The AgNPs in the range of size from 5 to 35 nm were found to enhance the microbicidal activities of the Na‐CMC films.

This article studies feasibilities of making an implant-film for treatment of burn wound, based on silver nanoparticles (AgNPs) stabilized by sodiumcarboxymethylcellulose (Na-CMC) with degrees of substitution (DS) 0.65-0.90 and polymerization (DP) 200-600 synthesized using a photochemical method. The structural, physical and chemical, and physicalmechanical, burn wound healing properties as well as antimicrobial effects of implant-films containing the Na-CMC and AgNPs have been investigated. The shape, quantity, and size of the AgNPs embedded into the Na-CMC films were determined by UV-Vis spectroscopy, dynamic light scattering (DLS), atomic force microscopy (AFM) and transmission electron microscopy (TEM). It was found that the increase of silver nitrate concentration in solution of Na-CMC followed by photoirradiation leads to changes of AgNPs size and shape. It was found out that Na-CMC films containing AgNPs in the size ranging from 5 to 35 nm had enhanced the microbicide effects and burn wound healing properties within 14 days.

“…Comparative antimicrobial activity of silver nanoparticles with different sizes and shapes are presented in Table 4. Na-CMC hydrogels containing silver nanoparticles with spherical structures and sizes 5 -35 nm showed a highest activity against Staphylococcus epidermidis and Candida albicans due to high values of their surface area and ability to penetrate into the cell nucleus [16] [17]. Na-CMC hydrogel contained rod-shape silver nanoparticles with l = 50 -140 nm and d = 15 -40 nm was less active than hydrogels contained silver nanoparticles with spherical structure, but they are more active in compare to Na-CMC hydrogel contained silver ions.…”

Stable silver nanoparticles in a sodium-carboxymethylcellulose hydrogel with a substitution degree of 0.65 -0.85 and polymerization degree of 200 -600 have been synthesized. Physical, chemical properties and antimicrobial activity of sodium-carboxymethylcellulose hydrogels contained silver nanoparticles were studied. The shape, number and size of silver nanoparticles (SNP) incorporated into the structure of hydrogels of sodium-carboxymethylcellulose were studied by using UV-VIS spectroscopy, transmission electron and atomic force microscopy. It was found that the silver nitrate concentration increase in sodium-carboxymethylcellulose solutions, as well as photoirradiation of the hydrogel lead to the changes of the silver nanoparticles size and shape. The studies have shown that the spherical silver nanoparticles of 5 -35 nm in the structure of sodium-carboxymethylcellulose hydrogel possess high bactericidal activity. Our results have shown that changing of size and shape of silver nanoparticles contributes to appearance of their biological activity.
