Synthesis of multifunctional fluorescent magnetic graphene oxide hybrid materials

Fluorescent magnetic graphene oxide hybrid materials have been fabricated by a multistep method. X-ray diffraction, transmission and scanning electron microscopy, fluorescence spectroscopy, Fourier transform infrared spectroscopy, vibration sample magnetometry, and energy dispersive spectroscopy were used to characterize the resulting material. The results showed that the materials have a saturation magnetization value of 22.0 emu/g at room temperature and exhibit a symmetrical and narrow emission peak at 544 nm. The resultant materials are able to carry an anti-cancer drug, 5-fluorouracil, with a load capacity of 0.24 mg/mg.
