Mussel Inspired Self-Expandable Tubular Hydrogel with Shape Memory Under NIR for Potential Biomedical Application

Abstract

We engineered a novel shape memory polymer (SMP), a nanocomposite hydrogel containing polydopamine nano spheres (PDNs) as a self-expandable tubular hydrogel under near infrared(NIR). When NIR is applied to the nanocomposite hydrogel, the (PDNs) nanoparticle absorbs the light, which is dissipated locally as heat, to become the driving force of shape transition behavior. Since the fabricated PDN material has good mechanical properties, including rapid self-expandability and good biocompatibility, therefore a self-expandable material developed with good heating property under (NIR) irradiation might be useful for many biomedical applications such as the treatment of coronary artery disease.
