چکیده
Recent self-assembly of ultra-bright fluorescent colloidal mesoporous (nanoporous) silica particles is highlighted. The particles can be up to two others of magnitude brighter than polymeric particles of comparable size assembled with quantum dots. Comparing with the maximum fluorescence of free dye in the same volume, the particles can show fluorescence which is higher by more than three orders of magnitude. We discuss the nature of the high brightness of these particles, existing problems, potential applications and prospects.

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...

Fluorescent particles have broad applications in tagging, tracing, and labeling. Fluorescence is typically generated through incorporation of either inorganic or organic fluorescent dyes into the particle s material. While inorganic dyes are typically more stable, their number and compatibility is rather restricted. The large variety of organic dyes makes them attractive for creating fluorescen...
