Synthesis and characterization of basil seed mucilage coated FeO magnetic nanoparticles as a drug carrier for the controlled delivery of cephalexin.

A novel drug delivery system, loaded the drug cephalexin on the basil seed mucilage coated magnetic nanoparticles (FeO@BSM-CPX) was prepared and characterized by means of X-ray diffraction (XRD), Furier Transform Infrared (FTIR), Field Emission Scanning Electron Microscope (FESEM), Vibrating Sample Magnetometer (VSM), Transmission Electron Microscopy (TEM), and Anti-bacterial, and Specific Surface (BET). By comparing the size of the uncoated nanoparticles (12nm) and the size of the coated magnetite nanoparticles (6nm), it was found that with the mucilage coating being put on the magnetite nanoparticles, the size of the nanoparticle cores has also decreased. The optimum pH results showed that the higher adsorption capacity occurs when cephalexin is cationic at pH2.
