Abstract: A method of synthesizing and a method of curing cancers using a nano device are disclosed, the nano device comprising: a framework comprising a structure formed by Si—O—Si covalent bonds and a plurality of mesopores configured to store drug cargos therein by disulfide covalent bonds; and an independent and separate chitosan layer, deposited directly on the framework. The chitosan layer is designed to coat and protect said framework layer from leaking the drug cargos in a first condition and to degrade so as to expose the drug cargos in a second condition. The framework releases the drug cargos by allowing a predetermined concentration of glutathione to break the disulfide (S—S) covalent bonds.

Abstract: This patent mentioned the synthesis of new metal-organic framework based on hexameric titanium-oxo cluster. The novel material, termed MOF-902, was successfully synthesized and its crystal structure uncovered the 2-Dimensional (2D) layer structure generated by the link of trigonal prism Ti6O6(OMe)(—COO)6 clusters and imine linear linking units. The permanent porosity of MOF-902 is 400 m2 g?1. The band gap energy of this material was found to be 2.5 eV which is suitable to catalyze the polymerization reaction of methacrylate monomers under visible irradiation.
