Molecular docking and antioxidant activity of Cleome simplicifolia assisted synthesis of cerium oxide nanoparticles

Abstract Bio-motivated CeO2 NPs were fabricated using plant extract of Cleome simplicifolia. The chemicals present in the plant extracts played pivotal role in the fabrication of CeO2 NPs. Initially, fabricated CeO2 nanoparticles were authenticate by using the XRD pattern which resembles a cubic structure. UV–Visible data estimated the band gap of CeO2 around 3.50 eV. SEM images revealed nearly monodisperse spherical shapes due to agglomerization of CeO2 NPs. DPPH assay of CeO2 NPs exhibited an excellent antioxidant property. Moreover, molecular docking of CeO2 NPs was investigated by new protein molecule.
