Fabrication of a 2D metal–organic framework (MOF) nanosheet colloidal system and investigation of its fluorescence response to pesticide molecules

A novel Zn-LMOF was synthesized and exfoliated into ultrathin nanosheets to construct a stable sol–gel sensing system. It can sensitively sense pesticides such as imidacloprid, nitenpyram and dinotefuran via fluorescence quenching effect with very low detection limit (LOD).
