Abstract:

Using a reverse-phase microemulsion polymerization method and an encapsulating method, polyoxometalates (POMs) K₆SiW₁₁TiO₄₀ incorporating starch microspheres have been prepared and structurally characterized by elemental analyses, IR, UV-vis, and NMR spectroscopy. The size of SiW₁₁TiO₄₀/starch particles is about 40–60 nm. The polyoxometalate encapsulated by a starch microsphere retains the parent structure. The starch microsphere is a good carrier, as it is able to enhance the antitumoral activity of POMs and decrease the toxicity of POMs as well.
