Abstract

Efficient intermolecular energy transfer from carbostyril 124-sensitized Tb(3+) to Eu(3+) in aqueous aggregates is reported. This energy transfer was also recapitulated on the cell surface of a human kidney cell line (HEK-293T) and imaged by fluorescence microscopy as an example for the applicability of this energy transfer probe for imaging in biological systems.

摘要

报道了从 carbostyril 124 敏化的 Tb(3+)到 Eu(3+)在水聚集物中的高效分子间能量转移。这种能量转移也在人肾细胞系（HEK-293T）的细胞表面上得到了重现，并通过荧光显微镜成像作为该能量转移探针在生物系统成像中应用的示例。
