Popis: In recent times, the searches for alternative materials to plastic is a popular topic, due to the danger that synthetic materials cause to the environment and humans. Among the promising natural polymers, chitosan (CS) is certainly one of the most suitable since it it is edible, non-toxic and derives from crustacean waste.- However, it is necessary to improve its physical properties to be widely applied in food packaging, whose market is dominated by synthetic plastic. In this work we have synthesized silver nanoparticles (AgNPs) using hot-plate and microwaves-based techniques, using Aloe Vera leaves extracts. The synthetic process follows the principles of green chemistry, since no toxic substance is used to obtain nanomaterials. These NPs, having dimensions
