RESUMEN
In The present project, a variety of MnFe2O4 (Mn) and Cr2Fe6O12 (Cr)-based nanocarriers (NCs) were synthesized as photosensitizer and NCs for delivery of chemotherapeutic curcumin (CUR) and provide a new structure for Photodynamic Therapy (PDT). For determining efficiency of NCs release study, MTT assay, lethal dose test and hemolysis assay were carried out. The release study showed the release of CUR from NCs was pH-dependent, but, every NCs had its own behavior for releasing the drug. The data acquired from the release study showed the CUR release from Mn can reach to over 90% at acidic media instead of 41% at neutral media. However, the CUR released from Cr were approximately equal as Cr had equal zeta potential at both media. Hemolysis activity and lethal dose test displayed the cytotoxicity of NCs was neglectable at both in vitro and in vivo study. Also, the results of anti-cancer activity assay (MTT assay) showed that both of Cr and Mn NCs are suitable systems for PDT. Therefore, the results demonstrated that Mn is suitable NCs for PDT and anticancer drugs delivery of therapeutic drugs.
