Facile approach to synthesize magnesium oxide nanoparticles by using Clitoria ternatea—characterization and in vitro antioxidant studies

Abstract

Facile approach to synthesize the metal oxide nanoparticles is getting an increased attention in various biomedical applications such as, to treat antibiotic resistant diseases. Magnesium oxide nanoparticles (MgOÁNPs) were synthesized by using Clitoria ternatea as the stabilizer in a green synthesis approach. The preliminary screening of MgOÁNPs in the presence of C. ternatea extract was observed by UV-visible spectrophotometer. X-ray diffraction (XRD) pattern have proved the crystalline nature of the MgOÁNPs; Photoluminescence (PL) measurement studies are used to identify the quality and defects in the crystal structure. FE-SEM with EDS has showed the size of 50-400 nm with specific binding energies. FT-IR has revealed the functional groups present in the plant extract and the peak at 521 cm -1 indicated the characteristic absorption bands of MgOÁNPs. The DPPH activity and reducing power assay of biologically synthesized MgOÁNPs could reach 65 % at a concentration of 150 lg/ml, respectively. From the results it was concluded that the biologically synthesized MgOÁNPs exhibit good antioxidant activity.

Blockage of both the extrinsic and intrinsic pathways of diazinon-induced apoptosis in PaTu cells by magnesium oxide and selenium nanoparticles

“…Among various metal oxides, magnesium oxide (MgO) is a functional semiconductor that has multiple applications in drug delivery, pharmaceutics, optoelectronics, cell signaling, and imaging because of its potent antimicrobial and antioxidant properties. 12,13 Previous studies have examined the protective effects of MgO NPs on oxidative stress parameters induced by malathion and chlorpyrifos, the widely used OP. 13,14 It was observed that malathion-induced cardiac cell toxicity is improved by administration of Mg as a result of increasing cardiac adenosine triphosphate (ATP) through active transport of Mg inside the cells.…”

Organic template-based ZnO embedded Mn3O4 nanoparticles: synthesis and evaluation of their electrochemical properties towards clean energy generation

“…[34][35][36] In this context, successive phytosynthetic routes have been investigated and reported, 37,38,[42][43][44][45][46] and have many advantages in terms of reduced toxicity, and the simplicity of method over the chemical synthesis approach. 39,40,83 In the present study, bio-templated mixed metal oxides have been investigated as a facile, greener nanomaterial with enhanced surface properties to replace chemically synthesized material. Thus, the focus of the present study is the synthesis of ZnO/Mn 3 O 4 nano-material using leaf extracts of the Olea ferruginea Royle (OFR) plant taken from Azad Jammu Kashmir, Pakistan.…”
