Abstract

A homogeneous assay is reported using Ru(phen)₂(dppz) ²⁺ and a K⁺-binding aptamer for the selective and sensitive detection of a target oligonucleotide and potassium ions, based on reduction in fluorescence emission according to the formation of the G-quadruplex structure from the aptamer in the presence of K⁺.
