A zinc-coordinated cascade-responsive therapeutic nanoassembly for remodeling the pathological microenvironment and restoring mitochondrial homeostasis in spinal cord injury
{{output}}
Secondary injury after spinal cord injury (SCI) is sustained by coupled oxidative stress and inflammation, which drives neuronal apoptosis and bioenergetic failure. Here, a cascade-responsive Zn2+-centered nanoassembly (Zn-PC/PA@Gel) is constructed through ste... ...
