采用萘胺基探针荧光猝灭法检测混合水介质中HgII、FeII和FeIII的含量。这些敏感的金属离子与探针结合形成1:1的配合物。研究了探针在不存在金属离子和存在金属离子时的时间分辨荧光和量子产率。计算了探针与敏感金属离子的结合程度。探针在其他金属离子存在下的灵敏度是用竞争性结合研究来检验的。该探针在体外和体内研究中对HgII表现出敏感性。这种多分析物探针在细胞成像和逻辑门方面具有潜在的生物学应用。
A naphthylamine-based probe was utilized for the detection of HgII, FeII and FeIII in mixed aqueous media by fluorescence quenching. These sensitive metal ions bind with the probe by forming a 1:1 complex. The time-resolved fluorescence and quantum yield of the probe in the absence as well as in the presence of metal ions were investigated. The extent of binding of the probe with sensitive metal ions was calculated. The sensitivity of the probe in the presence of other metal ions was examined using competitive binding studies. The probe displayed sensitivity towards HgII during in vitro as well as in vivo studies. This multianalyte probe has potential biological applications in cell imaging and in logic gates.
