Abstract (en)
[origin: WO2008100163A1] The subjects of the invention are a method of manufacturing silver nanoparticles of 1 to 350 nm in size, a method of manufacturing cellulosic fibers and nanofibers containing silver nanoparticles, fibers and nanofibers containing silver nanoparticles, the use of silver nanoparticles to the manufacture of cellulosic fibers and nanofibers and a wound dressing that contains silver nanoparticles. Silver nanoparticles are characterized by a considerable and selective biological activity due to which they are bactericidal, bacteriostatic and fungicidal. Advantages of nanoparticle-sized silver are its very large active surface that enables its use at very low concentrations, no risk of increasing susceptibility to mycosis and non-causing potentially hazardous mutations of bacteria. According to the invention presented, silver nanoparticles can be employed directly in the form of spinning solution of cellulose for the manufacture of cellulosic fibers and nanofibers of bactericidal properties. The silver nanoparticles are obtained b reducing water-soluble silver salts in the presence of an aqueous solution of N-methylomorpholine N-oxide.
