文摘

A colorimetric sensor for hydrogen sulfide was developed using G-quadruplex DNAzyme. This sensor utilize direct inhibition of active site in G-quadruplex DNAzyme by hydrogen sulfide. This sensor was selective for hydrogen sulfide in the presence of other anions. The detection limit of this colorimetric sensor system is estimated to be 410 nM.
