Ratiometric Displacement Approach to Cu(II) Sensing by Fluorescence
Abstract
A chelation-enhanced fluorescence method for the detection of paramagnetic copper(II) ions is developed. Two dyes with unequal metal ion binding constants are used, each giving strong fluorescence enhancement in the presence of a diamagnetic reporter ion such as cadmium(II). Upon presentation of copper(II) to a 1:1:1 mixture of the two dyes and cadmium(II), the Cd(II) is displaced from one dye to the other, resulting in quenching of one dye by the Cu(II) and enhancement of the weaker binding dye by complexation of the Cd(II). Although several criteria must be met, this method holds promise for analysis of a wide range of analytes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
