Biosynthesis, characterization and antimicrobial activity of copper oxide nanoparticles (CONPs) produced using brown alga extract ( Bifurcaria bifurcata )

摘要: Recently, biosynthesis of nanoparticles has attracted scientists’ attention because the necessity to develop new clean, cost-effective and efficient synthesis techniques. In particular, metal oxide are receiving increasing in a large variety applications. However, up now, reports on biopreparation characterization nanocrystalline copper relatively few compared some other oxides. this paper, we report for first time use brown alga (Bifurcaria bifurcata) dimensions 5–45 nm. The synthesized nanomaterial is characterized by UV–visible absorption spectroscopy Fourier transform infrared spectrum analysis. X-ray diffraction confirms formation crystalline nature nanomaterial. Further, these were found exhibit high antibacterial activity against two different strains bacteria Enterobacter aerogenes (Gram negative) Staphylococcus aureus positive).
