Abstract: A superhydrophilic wool fabric with wash fastness and a preparation method thereof are disclosed. Nanometer particles are grafted on the fiber surface of the superhydrophilic wool fabric with wash fastness by chemical bonds. The nanometer particles include nanometer silicon dioxide whose particle diameter is 10-800 nm. Based on the total mass of the superhydrophilic wool fabric with wash fastness, the amount of the nanometer silicon dioxide is 0.05-5% by mass.

Abstract: The present invention relates to the preparation method of a hollow mesoporous silica sphere coated with gold shell and its use in tumor therapy. In the present invention, the hollow mesoporous silica sphere is made as core and its surface is uniformly coated with the gold shell. The antitumor medicine is loaded in the hollow mesoporous silica sphere and the tumor specific targeting agent is coupled with the surface of the gold shell. The particle size of the hollow mesoporous silica sphere and the thickness of the gold shell are controllable. Based on the Mie Scattering Theory, the hollow mesoporous silica sphere coated with gold shell can adjust its absorption in near-infrared area and convert the light energy of infrared laser into peripheral heat which can kill the malignant tumor cells.
