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...
متن کاملLiposome Encapsulation of Fluorescent Nanoparticles: Quantum Dots and Silica Nanoparticles
Quantum dots (QDs) and silica nanoparticles (SNs) are new classes of fluorescent probes that overcome the limitations encountered by organic fluorophores in bioassay and biological imaging applications. We encapsulated QDs and SNs into liposomes and separated nanoparticle-loaded liposomes from unencapsulated nanoparticles by size exclusion chromatography. Fluorescence correlation spectroscopy w...

متن کاملHighly sensitive detection of Shigella flexneri using fluorescent silica nanoparticles.
Robust signal amplification tactic is a good solution for improving detection sensitivity. Unprocessed fluorophores have many limitations. Here we describe an effective strategy for highly sensitive detection of bacteria by using fluorescent conjugated nanoparticles. The nanoparticles were synthesized using silica as matrix. Fluorescein isothiocyanate distributed in the matrix. S. flexneri spec...
