A highly sensitive and selective “turn-on” fluorescent probe for detection of fleroxacin in human serum and urine based on a lanthanide functionalized metal–organic framework

A novel luminescent probe based on a Eu³⁺ functionalized MOF hybrid (Eu³⁺@1) with high sensitivity and selectivity has been proved to possess enormous potential for the determination of fleroxacin in human serum and urine.
