Biodegradable zein–polydopamine polymeric scaffold impregnated with TiO ₂ nanoparticles for skin tissue engineering

nanoparticle-impregnated zein-polydopamine-based nanofibrous scaffold was investigated, and its potential as a suitable wound dressing material was demonstrated. Further, the influence of nanotopographic structure on improved adhesion, proliferation and migration of cells was ascertained through in vitro assays. The constructive results obtained were well corroborated with the in vivo excisional wound healing experiment. Thus, the competence of the prepared nanofibrous scaffold was examined both in vitro and in vivo and demonstrated to be an alternative, cost-effective biomaterial for skin tissue engineering applications.
