Hierarchical Capillary Coating to Biofunctionlize Drug-Eluting Stent for Improving Endothelium Regeneration

Scheme 1

Schematic illustration of the hierarchical coating on the cardiovascular stent for regulating the intimal regeneration. The capillary-based wicking action could realize the distinctive real-time loading of VEGF during the surgery, which preserved the bioactivity of VEGF and impressively enhanced endothelium recovery while maintaining the inhibition of SMC proliferation after implantation.
