摘要
Bionanoprobes with high dispersion stability in water, excellent photostability, and biocompatibility were prepared by encapsulating [Eu(tta)3dpbt] (tta = thenoyltrifluoroacetonato, dpbt = 2-(N,N-diethylanilin-4-yl)-4,6-bis-(3,5-dimethylpyrazol-1 -yl)-1,3,5-triazine) in water-dispersible poly(methyl methacrylate-co-methacrylic acid) nanospheres and modifying the nanosphere surfaces with a monoclonal antibody (see scheme). The bionanoprobes exhibited excellent performance in the target-specific imaging of live cancer cells. (Figure Presented) © 2010 Wiley-VCH Verlag GmbH&Co. KGaA, Weinheim.
