摘要

Micro/nanorobots represent a groundbreaking advancement in nanotechnology, with applications spanning medicine, environmental remediation, and industrial processes. A major challenge in their development is achieving efficient and biocompatible propulsion. Enzyme-driven propulsion, particularly using catalase, offers a promising solution due to its ability to decompose hydrogen peroxide (H₂O₂) into water and oxygen, generating thrust for autonomous movement. Compared to metal-based catalysts, catalase-powered systems exhibit superior biocompatibility and lower toxicity, making them ideal for biomedical applications. This review explores the role of catalase in micro/nanorobot propulsion, highlighting self-propulsion mechanisms, different nanorobot types, and their applications in drug delivery, infection treatment, cancer therapy, and biosensing. Additionally, recent advancements in biodegradable enzyme-powered nanorobots and their potential in overcoming biological barriers are discussed. With further research, catalase-driven nanorobots could revolutionize targeted therapy and diagnostic techniques, paving the way for innovative solutions in nanomedicine.
