Abstract
We reported a reactive probe for HSO3(-), which showed a colorimetric and ratiometric fluorescence response to HSO3(-) with fast response (t1/2 = 20 s), good specificity and low detection limit (3.0 nM). The probe was cell membrane permeable and successfully used for visualizing trace SO2 derivatives in living cells.
摘要
我们报道了一种用于HSO3(-)的反应性探针，它对HSO3(-)表现出比色和比率荧光响应，响应迅速（t1/2 = 20秒），特异性良好且检测限低（3.0 nM）。该探针具有细胞膜通透性，并成功用于可视化活细胞中的痕量SO2衍生物。
