Nano-sized curcumin-loaded super-paramagnetic iron oxide nanoparticles (CUR-OA-SPIONs) were synthesized chemically by co-precipitation method using oleic acid as a stabilizer and Myrj 52 as a surfactant. The synthesized nanoparticles were characterized for their shape, size, surface morphology, electrokinetic potential, magnetic properties
