Fullerene C60 functionalized γ-Fe2O3 magnetic nanoparticle: Synthesis, characterization, and biomedical applications.

Hybrid magnetic nanoparticles composed from C60 fullerene and γ-Fe2O3 were synthesized by hydrothermal method. XRD, FT-IR, VSM, SEM, and HR-TEM were employed for characterizations. The magnetic saturation value of C60-γ-Fe2O3 magnetic nanoparticles was 66.5 emu g(-1). Concentration of Fe in nanoparticles as determined by ICP-OES was 40.7% Fe. Particle size of C60-γ-Fe2O3 magnetic nanoparticles was smaller than 10 nm. Maximum adsorption capacity of C60-γ-Fe2O3 for flurbiprofen, a non-steroidal anti-inflammatory drug, was calculated from Langmuir isotherm as 142.9 mg g(-1).
