Facile preparation of Fe2O3 nanoparticles mediated by Centaurea alba extract and assessment of the anti-atherosclerotic properties
This research work attempts to synthesize iron nanoparticles with Centaurea alba extract. The reported synthesis method serves to be more effective over conventional physical and chemical methods, which is found to be cost effective, recyclable, biocompatible and prevents oxidation of iron oxide nan...
