Replacing autologous nerve grafts with conduits is the prevailing direction for treatment of peripheral nerves, though repair hollow remains unsatisfactory. In this study, cysteinylated zein (l-Zein) was prepared through a disulfide exchange reaction between bonds cysteine (Cys) and those (Zein). Subsequently, electrospinning utilized to fabricate loaded berberine (BBR) by means hydrogen bonding physical encapsulation. Hydrogels were ionic cross-linking Zein pectin (Pec), subsequently melatonin (MT) graphene oxide (GO) adsorption A hydrogel then injected into catheter form composite conduit (l-ZBZPGM). The hydrogels exhibited continuous porous network structure pore size distribution 100 200 μm. Most porosity exceeding 70% compressive modulus 0.42 ± 0.025 MPa. residual mass ratio 35.15% 1.87% at end 30 d degradation period, achieved peak release on day 18 rate 83.31% 3.64%, had an electrical conductivity 1.23 0.482 × 10-3 S cm-1, meeting requirements repair. lack cytotoxicity anti-inflammatory antioxidant properties l-ZBZPGM demonstrated using RSC96 cells Raw264.7 cells. Additionally, stimulation experiments, it proven that addition GO can promote proliferation biological materials used in study are simple composition, their products may have minimal impact microenvironment. findings suggested more conductive regeneration.
