Dear Editor,Phenotypic drug discovery,which observes compound effects on physiology,has given way to targeting specific molecules,but has revived by using modern methods to find drugs based on therapeutic outcomes in disease models(Vincent et al.,2022).Osteoarthritis(OA)is a prevalent chronic joint disorder,primarily affecting knee joints,with osteoclast activation due to low-grade inflammation resulting in increased bone resorption and structural changes in the joint(Katz et al.,2021).This imbalance and the discharge of inflammatory mediators perpetuate the cycle of inflammation and tissue ***,controlling inflammation and modulating osteoclastogenesis are critical therapeutic targets for managing OA.

As a class of functional crystalline porous materials, metal-organic frameworks(MOFs) gained rapid development in the past three decades and a large number of MOFs with ordered structures, high surface areas, and functionalized channels have been investigated. MOFs and MOF-derived/composite materials show great potential in many application fields. In this review, we discussed the main applications of MOFs and MOF-derived/composite materials in small molecule storage, separation, luminescence, sensing, multitype catalysis, and energy storage. In addition, challenges and problems in the future research of MOFsrelated fields are also discussed.
