Silver Nanoparticles Stabilized Using Chitosan Films: Preparation, Properties and Antibacterial Activity

Popis výsledku v původním jazyce

In this work we present silver nanoparticles coated with chitosan films synthesized by a simple, environmentally friendly method. Silver nanoparticles were prepared and stabilized by reduction of silver nitrate with chitosan without addition of harmful reduction agents. The presence of silver nanoparticles in the solid films was studied by the X-ray diffraction spectroscopy and X-ray photoelectron spectroscopy. Solid films were dissolved and the solution was observed by the ultraviolet visible spectroscopy and transmission electron microscopy. The amount of silver in the solid samples was studied by atomic absorption spectroscopy. Antibacterial activity of solid films with silver nanoparticles was tested by disc test on two bacterial strains, Gram-positive Staphylococcus epidermidis and Gram-negative Escherichia coli. The presence of silver nanoparticles was confirmed both in solid film and in solution by the above mentioned methods. The films exhibited strong antibacterial activity ag
