The present work is focused on preparation and characterization polysaccharide films based on methylcellulose. Films were doped with silver nanoparticles (AgNPs). AgNPs were prepared and stabilized by reduction of silver nitrate. Polyethylene glycol and glycerol were used as additives for better material properties of methylcellulose films. Properties of these films were analyzed with a number of analytical techniques. Wettability and water absorption of films were evaluated. Concentration of the AgNPs released into the solution during dissolution was studied by atomic absorption spectroscopy. The presence of AgNPs in solutions and solid films was monitored by the ultraviolet–visible spectroscopy. Solid films were dissolved at different temperatures and release of AgNPs from the film was observed during the dissolution time by the ultraviolet–visible spectroscopy. The presence of AgNPs was confirmed both in the solid films and in the solutions by the above mentioned methods. It was found that additives changed materials properties. Our research was aiming on use of these films in medicine as a new type of wound dressing with antibacterial properties or as a drug delivery system.Keywords: Polysaccharides films, silver nanoparticles, methylcellulose
