Hollow porous silica nanosphere capable of controlling size, number of pores and shell thickness, and manufacturing method thereof

摘要

The present invention provides a method for producing a porous silica nanosphere capable of controlling the size and number of gaps in the shell of a porous silica nanosphere and the thickness of the shell of a porous silica nanosphere having gap holes on the surface thereof, and in the internal blank space of the porous silica nanosphere. A method for preparing a hollow porous silica nanosphere that can be used as a drug carrier by loading a drug and allowing the drug to be slowly released, and to the porous silica nanosphere, comprising: synthesizing a template polymer having a functional group on the surface ; Synthesizing porous silica nanospheres by depositing a silica precursor on the surface of the template polymer in a basic solution; And sintering and removing the template polymer to synthesize a hollow porous silica nanosphere. It provides a hollow porous silica nanosphere production method and the hollow porous silica nanosphere.
