These soluble-in-water polymer salts allowed us to produce, in an eco-friendly and facile method, silver nanoparticles (AgNPs) with better control on size and polydispersity, even at large silver concentrations than their corresponding chitosan sample. Chitosan salt-based materials (films and scaffolds) were analyzed in terms of antibacterial properties against Staphylococcus aureus ATCC23915 or Pseudomonas aeruginosa ATCC 27853. 3D scaffolds enhanced the effect of the chitosan-AgNPs combination compared to the equivalent films.engATTRIBUTION 4.0 INTERNATIONALhttps://creativecommons.org/licenses/by/4.0/journal articlehttps://doi.org/10.1016/j.ijbiomac.2023.123849open access615.46546ChitosanSilver nanoparticlesNanocompositeMaterialesQuímica inorgánica (Farmacia)3312 Tecnología de Materiales
