title: Visual detection of potassium by a cyanine dye supramolecular aggregate responsive to G-quadruplex motif transition.
abstract: A supramolecular probe is designed for visual detection of potassium based on a novel cyanine dye aggregate recognizing the motif transition of telomeric G-quadruplexes under the Na(+) background. The practical application for colorimetric measurement of urine potassium has been tested.
