The tubular porous poly(ɛ-caprolactone) (PCL) scaffold was fabricated by electrospinning. After then, the scaffold's surface was firstly eroded by hexyldiamine to endow amine group, and heparin was covalently grafted to the surface to get surface heparin modified scaffold (ShPCL scaffold). It was found that ShPCL scaffold can induce smooth muscle cells(More)
Heparin based polymer drug which could self-assemble into sphere micelle in water was firstly prepared by grafting paclitaxel (PTX) into the hydroxyl of heparin via aconitic bond as pH sensitive spacer. Positive charged drug DOX·HCl and cationic folic acid (CFA) can be further loaded into the polymer drug via electrostatic interaction in aqueous solution so(More)
