Histone demethylases (HDMs) are vital players in epigenetic regulation and important targets in cancer treatment, but effective molecular tools for analyzing HDMs activity are still limited. Interestingly, we found that the process of Ag+-triggered oxidation of O-phenylenediamine (OPD) to 2,3-diaminophenazine (OPDox) could be efficiently inhibited by formaldehyde (HCHO), with the decrease of fluorescent and colorimetric signals from OPDox. Accordingly, we developed a novel label-free fluorescent and colorimetric dual-readout assay for HDM
