Scheme 1. — (A) Structural formula of the clickable mussel-inspired peptide [3,4-dihydroxy-l-phenylalanine (DOPA)₄-polyethylene glycol (PEG₅)-Azide], NO-generating organoselenium [dibenzylcyclooctyne (DBCO)-SeCA], and EPC-binding peptide (targeting peptide, TPS-DBCO). (B) Surface cografting on representative vascular stents through mussel-inspired coordinative interactions and bioorthogonal click chemistry. (C) The catalytic reactions of nitric acid (NO) generation process by SeCA and the proposed mechanism of SeCA/TPS cografted stents for antiplatelet adhesion, SMC inhibition, EPC homing, EC growth, and reendothelialization.
