A magnetic nanoscale metal–organic framework (MNMOF) as a viable fluorescence quencher material for ssDNA and for the detection of mercury ions via a novel quenching–quenching mechanism

Here, we propose a magnetic nanoscale metal–organic framework as a novel quenching material and reveal its quenching–quenching mechanism. It sensitively and selectively binds Hg( ii ) and a detection limit of 8 nM.
