Opis:: In the present study silver nanoparticles were obtained using the ability of chitosan to form chelate compounds with metal ions and taking advantage of its reducing properties. The reduction process was conducted at the temperature 60°C or applying γ radiation from 60Co cobalt source. A preliminary characteristic which allows us to realize the size of formed silver nanoparticles was made on the basis of the measurements of UV absorption and dynamic light dispersion.

Opis:: Chitosan as a dietary supplement has been used in the treatment of obesity due to its capability of binding bioactive compounds. A molecule of a cationic polymer, such as chitosan, may bind acid drugs. The aim of the study was to determine the binding capability of Ketoprofen and Naproxen sodium salt by chitosans contained in weight-loss supplements. The drug absorption was investigated by means of a dynamic method in a biopharmaceutical model imitating in vitro conditions including the required level of nutrients. Mean absorption of drugs by chitosan ranged from 92% to 96% depending on the environmental pH. The highest absorption rate was observed at above pH 7. Concluding, the studies confirmed that the investigated drugs interact with chitosan, what leads to decrease in their amount and affects the bioavailability of the drugs.
