A simple and rapid fluorescence sensing platform based on the MIL-53(Fe) MOF was developed for fast, highly selective and ultrasensitive direct determination of MeHg+.
In this work, Au nanoparticles self-assembled with covalent-organic frameworks via a 1 min process at room temperature, and the obtained nanocomposite was employed as a new type of surface-enhanced Raman scattering sensor for the recognition of polycyclic aromatic hydrocarbons with high sensitivity.
