Antibacterial membranes with a multicomponent system containing Ag, AgBr, Ti02, and hydroxyapatite as four active components were used to obtain more efficient antibacterial activity. Additionally polyurethane nanofiber webs containing silver nanoparticles using the electrospinning technique were obtained with the stability of nanoparticles after washing cycles...

Chemical reduction is the most frequently applied method for the preparation of silver nanoparticles as stable, colloidal dispersions in water or organic solvents. However, a number of alternative green chemistry synthesis routes have been reported. Inspired by mussel adhesive proteins, a novel functional polyurethane based on hydrolyzable tannins that contain a number of catechol groups was...
