design of a novel naked-eye sensor based on the alr-mr-hg2+ system: monitoring of biologically important anions

In the present work, we proposed a novel naked-eye sensor based on the alr-mr-hg2+ system with short assay time and high sensitivity to detect biologically important anions in real samples. under the optimal conditions, the naked-eye detection limits were 0.2 µm and 70.95 nm for hg2+ and carbonate ion respectively. the linear regions are obtained from 1.2 to 93.0 µm and 3.87 to 65.85 µm for hg2+ and carbonate ion respectively. furthermore, it was confirmed that the alr-mr-hg2+ probe has excellent selectivity, high sensitivity and quick response for carbonate.
