Unlocking Catalytic Activity via Tuning Fe 3d Spin State in Fe Dual-Atom Nanozymes with Atomically Dispersed Fe2-N6 Configurations for Reprogramming Immuno-Redox Microenvironment in Rheumatoid Arthritis
This study presents a high-spin Fe dual-atom nanozyme with an atomically dispersed Fe₂-N₆ configuration that, when encapsulated in a pH-responsive hydrogel, effectively treats rheumatoid arthritis by tuning the Fe 3d spin state to enhance ROS-scavenging catalytic activity, thereby reprogramming the immuno-redox microenvironment and inhibiting chondrocyte pyroptosis.
