Description
Summary:The silver oxide nanoparticle was successfully synthesized using floral waste by simple one pot, cost effective method. The complete formation of silver oxide nanoparticles was characterized by UV-spec, FT-IR, powder XRD. The morphological structure of synthesized Ag 2 O NPs was confirmation by FE-SEM. The biofilm inhibition and biofilm metabolic assay results were confirmed that the synthesized Ag 2 O NPs very effective against biofilm formation. In addition, exopolysaccharide and hydrophobicity degradation assays were supported to biofilm inhibition at 250 µg/mL concentration. In addition, the architectural and extracellular damages of K. pneumoniae were proved by CLSM and SEM. Finally, the reported hemolytic activity effect of synthesized Ag 2 O NPs shown at very low compared with CLSI guidelines, this might be due to the presence of the polyphenols of floral waste extract. Conclusively, the synthesized Ag 2 O NPs was eco-friendly nature and promising anti-biofilm agent against K. pneumoniae
