Abstract
1·Eu·BPS was developed as a luminescent lanthanide sensor for use in displacement assays for detection of d-metal ions by monitoring the changes in the europium emission, which was quenched for iron(II), with a detection limit of ∼10 pM (0.002 μg L(-1)) for Fe(II) in buffered pH 7.4 solution.
摘要
1·Eu·BPS 被开发为一种发光镧系元素传感器，用于通过监测 Eu 发射的变化来进行置换分析，以检测 d-金属离子，Fe(II)会使 Eu 发射猝灭，在缓冲 pH 值为 7.4 的溶液中，Fe(II)的检测限约为 10 pM（0.002 μg L(-1))。
