Enhancing Molecular‐Level Biological Monitoring with a Smart Self‐Assembling ¹⁹F‐Labeled Probe

Real-time monitoring of molecular transformations is crucial for advancements in biotechnology. In this study, we introduce a novel self-assembling ¹⁹F-labeled nuclear magnetic resonance (NMR) probe that disassembles upon interaction with various nucleotides. This interaction not only activates the ¹⁹F signals but also produces distinct signatures for each specific component, thereby enabling precise identification and quantification of molecules in evolving samples. We demonstrate the capability of this probe for real-time monitoring of adenosine triphosphate (ATP) hydrolysis and screening potential enzyme inhibitors. These applications highlight the probe's significant potential in enzyme analysis, drug development, and disease diagnostics.
