Research Article


A synthetic, dispersible magnesium aminoclay (MgAC) was synthesized in the present study. Besides, structural and spectroscopic detections were conducted to investigate the MgAC nanoclay. With a poor aqueous solubility, methotrexate (MTX) has been applied as a valid antitumor agent in recent years. In our research, an unobtrusive sol-gel process was carried out to manufacture the MgAC-MTX nanohybrids through entrapment of MTX over MgAC in situ. The final product was capable of desquamating and thus dispersed in water, equably. In comparison with rough MTX, the MgAC-MTX nanocomposite with a preferable treatment efficacy against MCF-7 cells was mainly attributed to the preeminent enhanced aqueous solubility, controlled release and the increased cellular uptake capacity. Moreover, with excellent anticancer function and hypotoxicity as vindicated in vivo, the MgAC-MTX nanohybrid was supposed to own the potency in the application of malignant tumors cure as a valid nanomedicine. It turned out that, by virtue of its high bioavailability, the MgAC-MTX nanohybrids with high bioavailability is deserving of further study for the treatment of cancers.
