Morphosynthesis of porous silica from biocompatible templates

Morphosynthesis of star-shaped titania-silica shells.

Synthesis of porous hollow silica nanostructures using hydroxyapatite nanoparticle templates.

Porous hollow spherical and rod-like silica nanoparticles were obtained via a surfactant templating method adopting hydroxyapatite (HAp) nanoparticles as an etchable core material.

Microstructured Porous Silica Obtained via Colloidal Crystal Templates

A novel scheme for using modified colloidal crystals as templates for silica polymerization is reported. 3D close-packed crystals of submicrometer latex spheres are assembled on a membrane surface by filtration. To induce silica polymerization, the particles are modified by adsorption of the surfactant hexadecyltrimethylammonium bromide. The colloidal crystals are then infused with a silica sol...

Synthesis and Characterization of Biocompatible and Size-Tunable Multifunctional Porous Silica Nanoparticles

In this work, size-controlled multifunctional mesoporous silica nanoparticles having large surface areas, embedded luminescence, high magnetization, and excellent aqueous dispersity have been successfully prepared by using a simple one-pot synthesis. The size and pore ordering of these particles can be easily controlled based on the number density of Fe3O4 nanoparticle nucleation sites introduc...

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.
