Synthesis of Tunable Theranostic Fe₃O₄@Mesoporous Silica Nanospheres for Biomedical Applications

Abstract

Tunable theranostic Fe3O4@mesoporous silica nanospheres: Tunable theranostic Fe3O4@mesoporous silica nanospheres for diagnosis and gene therapy have been designed. The tunable delivery doses of imaging probe and gene by Fe3O4@mesoporous silica nanospheres can be realized by the tunable magnetic cores and modification of surface charges. These Fe3O4@mesoporous silica nanospheres may act as a theranostic nanosystem due to good biocompatibility, effective MRI diagnosis and gene delivery capabilities.
