Advances in organometallic/organic nanozymes and their applications

Nanozymes, the next-generation artificial enzymes, are nanomaterials with enzyme-like characteristics and have been widely used in detection, disease diagnosis, biological therapy, and other fields. Among them, organometallic/organic nanozymes with organometallics/organics as the catalytic sites have enhanced catalytic activity due to their high catalytic site density. To date, many studies on organometallic/organic nanozymes have been reported, but these reports have not yet been highlighted in a separated review. Here, the research progress of organometallic/organic nanozymes in recent years is reviewed. Organometallic/organic nanozymes are classified according to the types of catalytic sites. The applications of organometallic/organic nanozymes in detection, imaging, therapy, filter, sensor, and battery are introduced. The challenge and future opportunity in this field are also discussed.
