Nanoparticles of iron oxide magnetic nanoparticles known as one of the most important in the past decade, the attention of many researchers and scientists have since expanded the use of the nanoparticles can be catalytic role, drug delivery, cancer treatment, treatment water contaminated with heavy metals and radioactive substances, used in the MRI, magnetic fluid and ... noted. In the present study, Fe۳O۴ MNPs synthesized in a green manner using aqueous extract of shepherd’s tea (Stachys lavandulifolia) (St-FeR۳ROR۴ RMNPs) were applied as a magnetically separable.Shepherd’s tea can be a good candidate for synthesizing nanoparticles and applying the phenolic compounds as reducing and capping agents. The green synthesized St‐FeR۳ROR۴ RMNPs as recyclable Nano catalyst could be used for further research on the synthesis of therapeutic materials, particularly in Nano medicine, to assist in the treatment of cancer. Iron oxide nanoparticles, due to their superparamagnetic behavior and surface modification properties, are considered to be suitable candidates in cancer therapy.
