A pH‐Switchable Cerium Single‐Atom Enzyme for Peri‐Implantitis Therapy via JAK‐STAT Signaling Axis‐Mediated Macrophage Reprogramming
ABSTRACT The development of high‐performance, environmentally adaptive enzyme‐mimicking catalysts for the treatment of peri‐implantitis (PI) is of great importance yet remains highly challenging. Herein, we report a high‐performance cerium single atom on B, N co‐doped carbon nanotubes enzyme (SAzyme), denoted as Ce‐BNC. Benefitting from its unique N/O‐coordinated electronic environment and reversible Ce 3+ /Ce 4+ redox cycle, Ce‐BNC exhibits an intrinsic pH‐switchable catalytic function, with acidic conditions favo …
