In this work, we used a titanium-based metal-organic framework (MOF, Ti-MIL125-NH2) as a novel enrichment platform to detect protein kinase A (PKA) activity and to screen relevant kinase inhibitors. This method took advantage of the highly specific recognition of phosphate groups by the Ti-MIL125-NH2 nanoparticle. In the presence of PKA and adenosine 5'-triphosphate (ATP), the fluorophore-labeled peptide substrate was phosphorylated, and the generated phosphopeptide could then specifically bind to the titanium sites of Ti-MIL125-NH2
