Enzyme-triggered inner filter effect on the fluorescence of gold nanoclusters for ratiometric detection of mercury(II) ions via a dual-signal responsive logic
Sensors and Actuators A: Physical（2020）
摘要
•Enzyme-triggered inner filter effect was designed for the ratiometric fluorescence.•A novel ratiometric fluorescence assay was proposed based on dual-signal response logic.•The proposed AuNCs/OPD/LACC sensing system showed satisfactory analytical properties toward Hg2+.
