- Abstract
- In this paper, we have synthesized multifunctional magnetic particles (MNPs) using by two different ferrite submicrometer paticles (Fe3O4@HP and CoFe2O4@HP) with different surface properties. Two different multifunctional particles have the same particle sizes within the error tolerance of 4.5%. The concentration measurement of the hematoporphyrin (HP) molecule indicates that the weight of HP molecules bonded to the surface of the Fe3O4 particles is smaller than that of the CoFe2O4 particles. Moreover, we have evaluated their biocompatibilities and photodynamic anticancer activities on mammalian cells. The two MNPs have demonstrated that they both have good biocompatibilities without any cytotoxicity and anticancer activities in the concentration range of 0-50 mu g/mL. Specifically, photodynamic-killing activities of both MNPs were measured to be 100% for CoFe2O4@HP, and were measured to be 37.9 +/- 3.5% and 9.2 +/- 2.5% for Fe3O4@HP in 25 and 50 mu g/mL of both MNPs. These results suggest that both MNPs can be safely used to for clinical photodynamic cancer therapy, although the CoFe2O4@HP showed a slightly better photo-killing efficacy compared with the Fe3O4@HP in prostate cancer.
