MOFs advanced several applications including biosensing . Lanthanide MOF was reported for the detection of ferric ions and vitamin C . The material was stable and can form high dispersion with high fluorescence emission signals. Fe(III) ions can selectively quench the fluorescence signal enabling a linear relationship in the concentration range of 16.6-167 μM with a limit of detection (LOD) of 16.6 μM (S/N ratio of >3) . Explosive materials such as nitroaromatic were detected using Zn-MOF .
