Fabrication Of Cobalt Oxide Nanoparticles Using Barringtonia Acutangula For Evaluation Of Antibacterial, Antioxidant And Protein Denaturation Activities
Keywords:
Barringtonia acutangla, Nanocobalt oxide particles, Antibacterial activity, Antioxidant activity, Protein denaturation studiesAbstract
Nanocobalt oxide particles were fabricated through an uncomplicated and sustainable process using dried fruit extract from Barringtonia acutangula. The successful formation of nanoparticles was evidenced by a characteristic absorption band observed between 300 to 750 nm. The presence of natural phytochemicals such as polyphenols and triterpenoids, which served as stabilizing agents by binding to the nanoparticle surface and supporting the formation of a stable Cobalt oxide lattice was confirmed using FTIR analysis. XRD analysis revealed the crystalline structure consistent with cobalt oxide. SEM images showed that the nanoparticles exhibited rough and irregular surface morphologies. EDX analysis confirmed uncontaminated state of the sample. The size was calculated to be 43 nm using TEM analysis. Additionally, the Cobalt oxide nanoparticles produced through the biological method worked against four different bacterial strains. They showed 91.27 % antioxidant activity and 59.6 % inhibition activity.
