Abstract
A 2-hydroxy-5-methyl-benzene-1,3-dicarboxaldehyde di-oxime based turn-on blue emission fluorescent probe was found to recognize both AsO2(-) and H2AsO4(-) in a purely aqueous medium in intra and extra-cellular conditions. Self-organization of the ligand in the absence and presence of AsO2(-) and H2AsO4(-) was investigated by DLS, optical microscopy, optical fluorescence microscopy and FE-SEM methods.
摘要
发现一种基于2-羟基-5-甲基苯-1,3-二甲醛二肟的开启型蓝色发射荧光探针能够在细胞内和细胞外条件下的纯水性介质中识别亚砷酸根离子（AsO2(-)）和砷酸根离子（H2AsO4(-)）。通过动态光散射（DLS）、光学显微镜、光学荧光显微镜和场发射扫描电子显微镜（FE-SEM）方法研究了在不存在和存在AsO2(-)及H2AsO4(-)的情况下配体的自组装情况。
