Antitumor effect of magnetite nanoparticles in cat mammary adenocarcinoma

The antitumor effect of a magnetic fluid was studied after direct inoculation into cat mammary tumors. An external magnetic field was used to retain the nanoparticles in the tumor tissue. After 2 month, the mammary tumor regressed very much in size and the microscopic exam revealed that the tumor cells massively endocytosed magnetic nanoparticles and entered in lysis process.
