Smart-responsive materials have attracted much attention in the enrichment of post-translational modifications proteins. In this work, for first time, we developed a smart strategy (MNPs-l-DOPA/PEI-SP) based on change hydrophilic properties spiropyran under regulation light and pH to realize controllable release intact glycopeptides. The mechanism possible binding were verified by theoretical calculations. platform MNPs-l-DOPA/PEI-SP was used screen glycoprotein biomarkers hepatocellular carcinoma (HCC) evaluate its cancer diagnostic monitoring performance. A total 3,864 N-glycopeptides containing 166 N-glycoproteins successfully identified serum samples early-stage HCC patients, while 3,266 193 glycoproteins normal control (NC) samples. This work not only provides new ideas efficient glycopeptides with smart-responsive material, but also broadens research possibilities biomarker discovery liquid biopsies.
