A fluorescent wearable platform for sweat Cl− analysis and logic smart-device fabrication based on color adjustable lanthanide MOFs

By integrating a flexible host material (cotton piece) and two fluorescent materials (DUT-101 and Ag⁺/Eu³⁺@UiO-67), a wearable sweat Cl⁻ monitoring platform has been prepared, and by designing Cl⁻ and fluorescence signal to logic circuit, a codec device was constructed that can be set as a mimetic “indicator light”.
