在温和的条件下(50℃甲醇溶液)合成了绿色荧光富氮量子点(N点)，并将其作为关断传感器用于快速、选择性地检测水溶液中的Hg2+和Ag+。通过加入乙二胺四乙酸(EDTA)也成功地区分了Hg2+和Ag+。这些N-点-汞和N-点-银还可以通过与N-点竞争Hg2+和Ag+来作为生物硫醇的化学传感器。
Green fluorescent nitrogen-rich quantum dots (N-dots) have been synthesized under mild conditions (50 °C in methanol) and applied as a turn-off chemosensor for the rapid and selective detection of Hg2+ and Ag+ in aqueous solutions. Distinguishing between Hg2+ and Ag+ was also successfully achieved simply through the addition of ethylene diamine tetraacetic acid (EDTA). These N-dots–Hg and N-dots–Ag could also be used as turn-on chemosensors for biothiols through their binding competition for Hg2+ and Ag+ with N-dots.
