AbstractDifferent cation-exchanged (K+, Na+ & Ca2+) nano-zeolites withi magnetite nanocomposites were synthesized and their suitability for drug loading was studied. Nanocomposites with different Fe3O4 contents were synthesized by adding magnetic Fe3O4 nanoparticles to the zeolite crystallization solution. The zeolite and its nanocomposites had high surface areas and enough adsorption capacity to load and release sufficient amounts of the chemotherapeutic doxorubicin. None or the zeolites or nanocomposites showed toxicity to SKBr3 or MCF-7 cancer cells. However, DOX@zeolite inhibits cell growth more than the non-encapsulated drug. Thus zeolites and their magnetite nanocomposites show potential as biocompatible medical devices.
