A colorimetric zinc(II) assay based on the use of hairpin DNAzyme recycling and a hemin/G-quadruplex lighted DNA nanoladder
A method is described for sensitive colorimetric determination of zinc(II) ions that uses (a) a Zn(II)-responsive hairpin DNAzyme that assists target recycling, (b) hybridization chain reaction, and (c) hemin/...
