Synthesis of monodisperse organosilica nanoparticles with hollow interiors and porous shells using silica nanospheres as templates.

A versatile method for the formation of monodisperse, bridged silsesquioxane nanoparticles with hollow interiors and porous shells has been developed using silica nanospheres as templates. Tunable size and shell thickness, as well as high surface areas and large pore volumes of the hollow particles, allow for practical application of these nanoparticles in many fields.

Synthesis and Characterization of Novel Modified and Functionalized Silica Nano-particles for Protein Delivery Applications

In this study, the synthesis, characterization and controlled release behavior of new Hollow Silica Nano particles (HSNPs) and Magnetic Silica Nano Particles (MSNPs) were studied. Magnetic Silica Nano particles (MSNPs), as drug delivery vehicles, were synthesized through the coating of Fe3O4 nano-crystals with silica layers. The HSNPs were obtained by removal of Fe3O4 templates with hydrochlori...

Aqueous-phase reactions on hollow silica-encapsulated semiconductor nanoheterostructures.

We introduce a facile and robust methodology for the aggregation-free aqueous-phase synthesis of hierarchically complex metal-semiconductor heterostructures. By encapsulating semiconductor nanostructures within a porous SiO(2) shell with a hollow interior, we can isolate each individual particle while allowing it access to metal precursors for subsequent metal growth. We illustrate this by Pt d...

Dual Templating Synthesis of Mesoporous Titanium Nitride Microspheres

Adv. Mater. 2009, 21, 1–5 2009 WILEY-VCH Verlag Gmb The synthesis of new porousmaterials remains an exciting area of research, in part because of their potential use in diverse applications. Materials having hierarchically porous nanostructures (such as bimodal mesoporous, meso–macroporous, or mesoporous–hollow materials) are particularly intriguing because they can uncouple overall mass transp...
