Abstract
Peripheral nerve injury (PNI) caused by injury may influence the patients' lifelong mobility unless there is an appropriate treatment. Tissue engineering has become a hot field to replace traditional autologous nerve transplantation due to its low surgical damage and easy-to-industrial advantages. Graphene (GR) is a kind of carbon nanomaterial with good electrical and mechanical properties that satisfy the demand for a good tissue scaffold for nerve regeneration. Herein, a novel and biosafe hydrogel is fabricated by using graphene and sodium alginate (GR-SA) together. This hydrogel not only can mimic the nerve growth microenvironment but also can promote the expression of neurotrophic substances and growth factors. Additionally, GR-SA hydrogel can significantly reduce inflammatory factors. Moreover, the results of both in vitro and in vivo tests demonstrate that GR-SA hydrogel has a promising prospect in PNI regeneration.
