| 中文摘要 | an easy prepared fluorescence turn-on and colorimetric dual channel probe was developed for rapid assay of hg2+ ions with high sensitivity and selectivity by using poly(acrylic acid)-templated silver nanoclusters (paa-agncs). the paa-agncs exhibited weak fluorescence, while upon the addition of hg2+ ions, agncs gives a dramatic increase in fluorescence as a result of the changes of the agncs states. the detection limit was estimated to be 2 nm, which is much lower than the hg2+ detection requirement for drinking water of u.s. environmental protection agency, and the turn-on sensing mode offers additional advantage to efficiently reduce background noise. also, a colorimetric assay of hg2+ ions can be realized due to the observed absorbance changes of the agncs. more importantly, the method was successfully applied to the determination of hg2+ ions in real water samples, which suggests our proposed method has a great potential of application in environmental monitoring.
