Biosynthesis of Cobalt Oxide Nanoparticles Using by Costus igneus Plant

Nanotechnology is gaining popularity in the 21st century for its capacity to modify metals into nanoparticles.Nanotechnology research suggests that green chemistry can manufacture valuable nanomaterials.The main of the study was to produce cobalt nanoparticles to determine its antibacterial property and to check its photocatalytic activity for degradation of dyes.It has become crucial to biosynthesize efficient, secure, and affordable nanoparticles that we use for the treatment of various infections, including surgical site infection and wound infection, due to the rapid development of microbial resistance to numerous antibiotic drugs.Cobalt oxide, a multifunctional, anti-ferromagnetic p-type semiconductor with an optical bandgap of ~2.00 eV, exhibits remarkable catalytic, chemical, optical, magnetic, and electrical properties.In our study, cobalt oxide nanoparticles were prepared by the green synthesis method using leaves of Costus igneus plant which also known as insulin plant.Costus igneus belongs to Costaceae family.X-ray diffraction and SEM techniques were used to confirm the synthesis of cobalt nanoparticles (XRD).
