Multifunctional hydrogels loaded with tellurium nanozyme for spinal cord injury repair.

ABSTRACT: Spinal cord injury (SCI) results in severe neurological deficits due to disrupted neural pathways. While the spinal cord possesses limited self-repair capabilities, recent advancements in hydrogel-based therapies have shown promise. Polyphenol-based hydrogels, known for their neuroprotective properties, offer a suitable microenvironment for neural regeneration. In this study, a novel poly(lipoic acid)/poly(dopamine) adhesive hydrogel was developed as a versatile platform for delivering therapeutic agents. This hydrogel was loaded with methylcobalamin, a neurotrophic factor, and tellurium nanoenzymes, potent antioxidants. The nanoenzymes effectively mitigated oxidative stress and inflammation, while methylcobalamin promoted nerve regeneration. The combined therapeutic effects of the nanoenz
