Ultrabright Fluorescent Mesoporous Silica Nanoparticles

Small, 2010
AbstractThe 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 ...

Building of multifluorescent mesoporous silica nanoparticles

Chemical Communications, 2009
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.

Preparation and Controllability of Mesoporous Silica Nanoparticles

2018
Mesoporous silica nanoparticles (MSNs) have attracted great attention because of their high surface area, large pore volume, transparency, biocompatibility, and high cell-uptake efficiency. Such unique properties allow the use of these materials such as catalysts, drug carriers, and optical materials. This chapter introduces the preparation of MSNs and
