Precise modulation of host-guest interactions between programmable Ln-MOFs (lanthanide metal-organic frameworks) and phosphate analytes holds immense promise for enabling novel functionalities in biosensing. However, the intricate relationship these structures remains largely elusive. Understanding this correlation is crucial advancing rational design fluorescent biosensor technology. Presently, there exists a large research gap concerning utilization Ln-MOFsto monitor conversion ATP to ADP, which poses limitation kinase detection. In work, we delve into potential amplify fluorescence response during kinase-mediated ATP-to-ADP conversion. Six Eu-MOFs were synthesized Eu-TPTC ([1,1':4',1″]-terphenyl-3,3'',5,5''-tetracarboxylic acid) was selected as ratiometric probe, most suitable high-precision detection creatine activity through differential from ADP. The molecular -level mechanism confirmed by density functional theory. Furthermore, simple paper chip-based platform constructed realize fast (20 min) sensitive (limit 0.34 U/L) biological samples. Ln-MOF-phosphate offer promising avenues assays hold precise customization analytical chemistry.
