- Abstract: Nanozymes are nanoscale materials with enzyme-mimicking catalytic properties.Nanozymes can mimic the mechanism of natural enzyme molecules.By means of advanced chemical synthesis technology,the size,shape,and surface characteristics of nanozymes can be accurately regulated,and their catalytic properties can be customized according to the specific need.Nanozymes can mimic the function of natural enzymes,including catalase(CAT),superoxide dismutase(SOD),and glutathione peroxidase(GPx),to scavenge reactive oxygen species(ROS).Reported findings have shown that nanozymes have the advantages of excellent stability,low cost,and adjustable catalytic activity,thereby showing great potential and broad prospects in the application of disease treatment.Herein,we reviewed the advances in the application of nanozymes in the treatment of joint diseases.The common clinical manifestations of joint diseases include joint pain,swelling,stiffness,and limited mobility.In severe cases,joint diseases may lead to joint destruction,deformity,and functional damage,entailing crippling socioeconomic burdens.ROS is a product of oxidative stress.Increased ROS in the joints can induce macrophage M1 type polarization,which in turn induces and aggravates arthritis.Therefore,the key to the treatment of joint diseases lies in ROS scavenging and increasing oxygen(O2)content.Nanozymes have demonstrated promising application potential in the treatment of joint diseases,including rheumatoid arthritis,osteoarthritis,and gouty arthritis.However,how to ensure their biosafety,reduce the toxicity,and increase enzyme activity remains the main challenge in current research.Precise control of the chemical composition,size,shape,and surface modification of nanomaterials is the main development direction for the future.
