Polysaccharides templates for assembly of nanosilver

•The review focuses on recent synthesis protocols for AgNPs using polysaccharides.•Polysaccharides were firstly applied as capping agents for metal nanoparticles.•Recently polysaccharides were used as both of reducer and stabilizer for AgNPs.•Pure AgNPs colloidal solutions are recently prepared by removable polysaccharides. Polysaccharides are particularly attractive in biomedical applications due to its biodegradability and biocompatibility. In addition to its ecofriendly effects and easy processing into different hydrogel shapes, made polysaccharides used on a large scale as suitable media for preparation of silver nanoparticles (AgNPs). In spite of, most of polysaccharides are water insoluble, but it has shown to be quite efficient capping agents and/or nanoreactor matrices for production of AgNPs. Several methods have been developed to get the benefit of multi-functionality for polysaccharides’ macromolecules in preparation of AgNPs. Therefore, recently, preparation of nanosilver using different polysaccharides have been the focus of an exponentially increasing number of works devoted to develop nanocomposites by blending AgNPs with different polysaccharides matrices. The current review represents a wide survey for the published studies which interested in using of polysaccharides in nanosilver preparations.
