Abstract Nerve repair remains a significant challenge due to the need for simultaneous microenvironmental regulation and functional reconstruction. Central to this process is the design of spatiotemporally adaptive biomimetic matrices that integrate mechanical support, biochemical signaling, and electrophysiological conduction. Self-healing hydrogels, endowed with dynamic repairability and programmable bio-functionality, have emerged as a promising class of materials for neural repair. Here, we review recent advances in the material platforms and design strategies of self-healing hydrogels, emphasizing three key mechanisms:(i) recapitulation of extracellular matrix cues to direct axonal outgrowth, (ii) controlled delivery of neurotrophic factors to modulate the regenerative microenvironment, (iii) incorporation of conductive components to restore electrical signal transmission. These convergent approaches establish a theoretical foundation for the rational design of next-generation biomate-rials. Finally, this review provides a perspective on the opportunities and future directions of self-healing hydrogels in advancing nerve repair and regeneration.
