A label-free and colorimetric turn-on assay for coralyne based on coralyne-induced formation of peroxidase-mimicking split DNAzyme

摘要

A simple, label-free and colorimetric method for coralyne detection was successfully established based on the coralyne-induced formation of split G-quadruplex-hemin DNAzyme. It can achieve a detection limit of 31 nM toward coralyne with excellent selectivity.
