- ... In this work, we discover an effective domino-effect-based detection mechanism for the rapid, high-selectivity, and ultrasensitive naked-eye colorimetric ratio assay of chromium(III) ion (Cr³⁺) in aqueous solutions. This naked-eye colorimetric ratio assay to Cr³⁺ relies on changes in absorbance properties that are due to the stimuli response of Cr³⁺ for the morphological transformation of silver n ...
