Electron Microscopy Study of TiO2 Nanoparticle in Mesoporous Silica

Mesoporous silica nanoparticle nanocarriers: biofunctionality and biocompatibility.

The study of ordered mesoporous silica materials has exploded since their discovery by Mobil researchers 20 years ago. The ability to make uniformly sized, porous, and dispersible nanoparticles using colloidal chemistry and evaporation-induced self-assembly has led to many applications of mesoporous silica nanoparticles (MSNPs) as "nanocarriers" for delivery of drugs and other cargos to cells. ...

Experimental study of TiO2 nanoparticle adhesion to silica and Fe(III) oxide-coated silica surfaces

New nano-architectures of mesoporous silica spheres analyzed by advanced electron microscopy.

Using template-containing silica microspheres as a precursor, novel ordered mesoporous silica nanoparticles with a narrow pore size distribution and high crystallinity have been synthesized by various hydrothermal merging processes. Several architectures like chains, dumbbells, triangles, squares and flowers have been discovered. The linking mechanisms of these interacting silica spheres leadin...

Polyvalent mesoporous silica nanoparticle-aptamer bioconjugates target breast cancer cells.

Spatiotemporal control over the delivery of therapeutic agents is an outstanding challenge to cancer treatment. By taking advantage of recent advances in DNA aptamer biology and mesoporous silica nanotechnology, we report a general approach to design and fabricate controlled release drug delivery systems that are able to effectively target cancer cells. Specifically, polyvalent mesoporous silic...
