Highlights: [•] A simple and sensitive colorimetric sensor for detecting Hg2+ was proposed. [•] The sensor based on the catalytic activity of hemin/G-quadruplex DNAzyme and T–Hg2+-T base pairs. [•] The sensor exhibited high sensitivity and high selectivity. [•] The sensor could be regenerated by using EDTA as the chelator. [ABSTRACT FROM AUTHOR]
