Mesoporous carbons prepared by nano-casting with meso- or non-porous silica nanoparticles

Mesoporous silica reinforced by silica nanoparticles to enhance mechanical performance.

Silica nanoparticle/mesoporous silica composite films were prepared by direct mixing with mechanical stirring and thermal imidization. The structural morphology was elucidated by scanning electron microscopy and the surface of the film was imaged by atomic force microscopy. The functional groups and desorption process of the films were elucidated by Fourier transform infrared spectroscopy and t...

Ultrabright fluorescent mesoporous silica nanoparticles.

The first successful approach to synthesizing ultrabright fluorescent mesoporous silica nanoparticles is reported. Fluorescent dye is physically entrapped inside nanochannels of a silica matrix created during templated sol-gel self-assembly. The problem of dye leakage from open channels is solved by incorporation of hydrophobic groups in the silica matrix. This makes the approach compatible wit...

Live-cell imaging of drug delivery by mesoporous silica nanoparticles

Building of multifluorescent mesoporous silica nanoparticles.

Bright and colourful nanocomposites are easily fabricated by doping and fixing one or two kinds of oligosilicate fluorescent dots encapsulated with dye molecules into the pore channels of mesoporous silica nanoparticles, which can engender abundant fluorescent signals with a single excitation wavelength.

Mesoporous silica nanoparticles: structural design and applications

The structural properties of mesoporous silica nanoparticles are reviewed. Different strategies for the introduction of functional groups are considered. Based on the architectural features of the material, the functionalization at defined regions of the particles is described, along with the properties emerging from the corresponding site-specific modifications of their chemistry. Many applica...
