G-Quadruplex-based DNAzyme as a sensing platform for ultrasensitive colorimetric potassium detection

Abstract

Two G-quadruplexDNAs are able to form peroxidase-like DNAzymes selectively promoted by K+, which provides a label-free approach to colorimetric detection of K+ with the highest sensitivity ever reported.
