Abstract. Stable silver nanoparticles in solutions containing sodium carboxymethylcellulose and cotton fabric have been synthesized, and their structure and physicochemical properties have been studied. The morphology and sizes of the silver nanoparticles formed in sodium carboxymethyl-cellulose solutions and on cotton fibres have been studied by atomic force microscopy and transmission electron microscopy. The investigations have showed that spherical silver nanoparticles with sizes of 5−35 nm are present in sodium carboxymethylcellulose solution, whereas 0.0086 wt.% spherical silver nanoparticles sized 2−30 nm formed in cotton fabric, exhibiting high bactericidal activity. Stabilization of silver nanoparticles has been promoted, maintaining the bactericidal and bacteriostatic activity of the modified cotton fabrics and textiles after washing five times. Stabilization of silver nanoparticles has preserved bactericidal and bacteriostatic activities during the washing of cotton fabrics and textiles on its base. The obtained bactericidal biomaterials, based on the cellulose-containing stabilized AgNPs, possessed an antifungal effect, prevented offensive odor, decreased the level of pathogenic germs, and preserved fungal disease. Cellulose-containing biomaterials could be used as a face mask for air filtration.
Key words. biomaterials, nanoparticles, sodium carboxymethylcellulose, cotton fabrics, atomic force micros-copy.
