受外界环境的影响小

具潜在生物亲和性

是一种新型的近红外荧光标记物。

Abstract

In an effort to prepare efficient and uniform biolabels

we have developed a novel fluorophore doped polystyrene/silica nanoparticles via sol-gel method. The copolymer precursors are obtained via copolymerizations of styrene and 3-methactyloxylpropyltrimethoxylsilane (KH570). The controlled hydrolysis and condensation of tetraethyl orthosilicate (TEOS) in sol-gel route leads to the formation of near-infrared ytterbium(Ⅲ)- (cyclopentadienyl)tris(diethylphosphito)cobaltate(Ⅰ) anion dyes doped polystyrene/silica nanoparticles. The method significantly reduces fluorescent dye leaching from the nanoparticles

and can be conveniently applied to various dyes molecules with no active group. Scanning electron microscope(SEM) images showed that the nanoparticles are very uniform spherical shape and monodispersed with a diameter of about 100 nm. The present near-infrared fluorescent nanoparticles possess with the values of facilitating bio-modification

biocompatibility

higher detection sensitivity and photo-stabi-lity

and will be well applied in cell recognition

bacterial detection

DNA analysis and so on.
