Chemical modification of biological materials is indispensable for enrichment of phosphorylated peptides. In this work, we synthesized a biomimetic honeycombed affinity chromatography (IMAC) adsorbent by preparing Crosslinked Chitosan, chelating aminomethyl phosphate decorated with Ti (IV) cation. The as-prepared CTSM@AMPA-Ti4+ composites with stable structure, low steric hindrance, and high Ti4+ loading amount were used as a promising adsorbent for enrichment of phosphopeptides. CTSM@AMPA-Ti4+ showed extremely high
