Ex vivo comparative study carried on C6 glioma-bearing rats after two hours of administration of free Dox, DOX-Ps 80-SPIONs and DOX-Ps 80-SPIONs combined with a magnetic field. The DOX NIR fluorescent assay revealed that magnetic field improves formulation deposition in tumor site when compared to free DOX and formulation alone.
