fluorescence probe has been designed and synthesized, and applied with a combined theoretical and experimental study. Research suggests that the probe can be used to sense Zn2 + and Hg2 + through selective turn-on fluorescence responses in the aqueous HEPES buffer (0.05M, pH = 7.4). The limit of detection (LOD) were determined as 1.46 × 10− 7 M (Zn2 +) and 2.50 × 10− 7 M (Hg2 +). Moreover, based on
已经设计并合成了荧光探针,并将其与理论和实验研究相结合。研究表明,该探针可用于在
水性
HEPES缓冲液(0.05M,pH = 7.4)中通过选择性开启荧光响应来检测Zn 2 +和Hg 2 +。检出限(LOD)的极限被确定为1.46×10 - 7 M(
锌2 +)和2.50×10 - 7 M(
汞柱2 +)。此外,基于DFT,对探针1,[1-Hg 2 + ]配合物和[1-Zn 2 +使用Gaussian 09程序(使用B3LYP函数)执行复杂的操作。基于自然键轨道(NBO)分析,研究了游离探针1和
金属配合物的电子性质。探针1也已经成功地应用于检测活细胞中的Zn 2 +和Hg 2 +。
