AB - PVGA, silver nitrate (AgNO ) and alginate (Alg) were cross-linked by using γ-ray radiation to obtain Alg/PVGA/AgNPs as a potential biomaterial. The hydrogel composition was characterized by several analytics methods, and the morphology was evaluated by scanning electron microscopy. The swelling behavior was tested in different mediums. The stability of AgNPs was followed by UV–Vis at 400  nm for 1 month. The hydrogel soil biodegradation was analyzed by visual observation, weight loss, Fourier transform infrared spectroscopy and thermogravimetric analy- sis for 120 days. A simple biodegradation mechanism has been proposed based on results. Additionally, cytotoxicity assays were carried out using NCTC 929 cells to observe cell viability. Keywords Biomaterial · Cross-linking · Biodegradation · Hydrogel · Silver nanoparticles Introduction Hydrogels are cross-linked hydrophilic polymers forming three-dimensional net- works, capable of absorbing and retaining a large volume of water in aqueous envi- ronments [1, 2], which allow a vast range of applications in biomedical, agricultural, veterinary and pharmaceutical areas [3]. The biomaterials used for wound dressings require proper exudates absorption, the maintenance of a moist environment around the wound and the protection of surrounding skin from maceration [4]. Therefore, hydrogels also exhibit the desired properties for wound dressing applications [5]. * G. M. Estrada-Villegas mayeli.estrada@ciqa.edu.mx CONACyT–Centro
