The pH impact in the culture medium was carefully discarded, but preserving the best conditions for solubilizing chitosan. The synergistic antibacterial effects were observed in the most combinations of AgNPs, chitosan and antibiotic, leading to a reduction from 37 to 97% in the minimum inhibitory concentration of the drugs. The mechanisms for the enhanced antimicrobial effects were proposed based on the investigations of the adsorptions of the drugs on the silver surfaces through surface-enhanced Raman scattering (SERS) spectroscopy.eng--BrasilJournal of the Brazilian Chemical Society-Surface chemistryAg+ ionLSPR spectroscopySynergism in the antibacterial action of ternary mixtures involving silver nanoparticles, chitosan and antibioticsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleBrasil, Marcelo S.
