英文摘要 | luminescent ruthenium(ii) complex covalently bound silica nanoparticles have been prepared and used as a probe for time-gated luminescence bioimaging. the new nanoparticles were prepared by copolymerization of a luminescent ru(ii) complex tris(5-amino-1,10-phenanthroline)ruthenium(ii) conjugated with 3-aminopropyl(triethoxy)si lane (aps-ru conjugate), free (3 -aminopropyl)triethoxysilane (aps) and tetraethyl orthosilicate (teos) in a water-in-oil reverse microemulsion consisting of triton x-100, n-octanol, cyclohexane and water in the presence of aqueous ammonia. characterization by transmission electron microscopy indicates that the nanoparticles are monodisperse, spherical and uniform in size, 64 +/- 4 nm in diameter. compared with the dye-doping nanoparticles, dye leakage of the new nanoparticles was remarkably decreased. in addition, it was found that the ru(ii) complex luminescence could be effectively enhanced with a longer luminescence lifetime (similar to 2.3 mu s) after forming the nanoparticles, which enables the nanoparticles to be suitable as a bioprobe for time-gated luminescence bioimaging applications. the nanoparticle-labeled streptavidin was prepared and successfully used for time-gated luminescence imaging detection of an environmental pathogen, giardia lamblia, with high specificity and sensitivity.
