聚肽/聚己内酯共混电纺纳米纤维的制备以及高效Thiol-Yne光化学表面改性
Fabrication of Electrospinning Polypeptide/Polycaprolactone Blend Nanofibers and Their Highly Effective Surface Modification by Thiol-Yne Photochemistry
摘要
Abstract
Synthetic polypeptides are unique biomaterials in the field of drug/gene delivery,tissue engineering and regenerative medicine.But electrospinning nanofibers used for tissue engineering are hard to be fabricated as a result of the rigid backbone of polypeptides caused by their α-helix and β-sheet conformations.In addition,the subsequent surface modifications of electrospinning nanofibers probably destroy the nanofibers.Thus,the fabrication and application of the electrospinning nanofibers of synthetic polypeptides are limited.In this work,electrospinning polypeptide/polycaprolactone (PCL) blend nanofibers were fabricated and then undergone surface modification by thiol-yne click chemistry,a fast non-destructive and highly effective access.Results of scanning electron microscope(SEM) and Fourier transform-infrared (FT-IR) spectroscopy showed that diameter and orientation of the nanofibers were determined by the polypeptide contents,and the surface modification did not destroy the surface morphology.X-ray photoelectron spectroscopy(XPS) confirmed the amine modification of the surface by the gentle thiol-yne method.关键词
