The application of novel ultrathin iron sulphide nanosheets in the nanotherapy of post-traumatic osteoarthritis
Degradable ultrathin iron sulphide nanosheets (FeSNSs) are developed and a PEGylated therapeutic formulation (FeS-PEG) is prepared that concurrently protects articular cartilage and stabilises subchondral bone by alleviating oxidative-stress-associated joint damage in PTOA, establishing FeS-PEG as a dual-functional, RO...
