Hydrogels are three dimensional cross linked polymers. They are highly desired because of their flexibility, hydrophilic nature, and . because they . are insoluble in water. Hydrogels are . flexible, highly . Suitable Mechanical properties. No cell adherence. Antibacterial properties (nanosilver. ). . Hydrogels comprise crosslinked polymeric matrices of renowned applications in distinct biotechnological areas, which may be synthesized by several techniques. In general and although very effective, many techniques required the need of monomers or solvents which require careful washing processes in order to be removed from the systems. On this aspect the synthesis of hydrogels developed by exposition to ionizing radiation offers advantages over the conventional methods, such as no need of monomers or toxic solvents, being also capable of sterilizing the product inside final packaging. In this work we report the loading and release of silver nanoparticles into radiation synthesized hydrogels to be applied as dressing for wound healing, from development stages to initial clinical evaluation in (Ethics Committee . for Drug Delivery and Regenerative Medicine.
