Abstract

We report a cerium metal–organic framework (ZJU-136-Ce) for the turn-on fluorescence sensing of AA. The fluorescence enhancement is attributed to the specific redox reaction between AA and Ce⁴⁺. The detection limit of AA reaches 7 nM, showing its potential for AA detection in the environmental industry and clinical medicine.
