Mercury(II) ions have emerged as a widespread environmental hazard in recent decades. Despite different kinds of detection methods reported to sense Hg 2+ , it still remains a challenging task to develop new sensing molecules to replenish the fluorescence‐based apparatus for Hg 2+ detection. This communication demonstrates a novel fluorescent sensor using UiO‐66‐NH 2 and a T‐rich FAM‐labeled ssDNA as a hybrid system to detect Hg 2+ sensitively and selectively. To the best of our knowledge, it has rarely been reported that a MOF is utilized as the biosensing platform for Hg 2+ assay.
