Monitoring of the hypertension drug felodipine is important to avoid unwanted side effects from high concentrations, but its sensitive detection remains challenging. Here, combining the advantages of ratiometric luminescence probes and near-infrared lanthanide luminescence sensing, multi-emission near-infrared magnetic core-shell nanoparticles based on lanthanide metal–organic frameworks are synthesized using a layer-by-layer method and shown to have excellent temperature and felodipine detection abilities.
