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

This is the authors' abstract. We don't add key points for this paper.

By integrating a flexible host material (cotton piece) and two fluorescent materials (DUT-101 and Ag ⁺ /Eu ³⁺ @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”.
