benzoxazinone based fluorescent probe for the specific and efficient detection of bisulfite ions in aqueous medium is described. The probe formed a bisulfite/sulphite adduct with an associated turn-on fluorescence response in the red wavelength region. No interference was observed in the detection process from all possible competing anions and molecules, including cyanide ion, cysteine, homocysteine and
描述了一种基于苯并嗪酮的荧光探针,用于特异性和有效地检测水性介质中的亚硫酸氢根离子。探针形成了亚硫酸氢盐/亚硫酸盐加合物,在红色波长区域具有相关的开启荧光响应。在检测过程中未观察到所有可能竞争的阴离子和分子(包括氰化物离子,半胱氨酸,高半胱氨酸和谷胱甘肽)的干扰。另外,该探针显示出快速的响应时间,低的检测限和细胞膜通透性。此外,该探针可激发两个光子,可对HeLa细胞以及小鼠不同器官的深层组织中的内源性亚硫酸氢根离子进行成像。
