Abstract
A rapid and efficient method based on molecular docking and isothermal titration calorimetry (ITC) was developed to identify effective adsorbents for the target peptide Ser‐Glu‐Ala‐Asp‐His (SEADH). Preliminary screening of five candidate adsorbents using molecular docking revealed that three suitable structures (A1, A2, and A3) either with or without coordination of Zn^2+^ should be effective. The three selected structures were then prepared and further screened by evaluating their affinities for the peptide SEADH using ITC. The screening results revealed that the adsorbent A2 coordinated with Zn^2+^ was the best adsorbent, and subsequent static adsorption experiments confirmed the reliability of the screening method. Further ITC analysis, combined with molecular docking, was performed to provide the possible adsorption mechanism.
