Recent Advancements in Near-Infrared Light-Propelled Nanomotors for Biomedical Applications.
Nanomotors (NMs) achieve autonomous motion by converting external energy into mechanical work, enabling them to perform complex tasks on demand. Among the various propulsion mechanisms for NMs, near-infrared (NIR) light propulsion has attracted significant attention due to its excellent biocompatibility, deep tissue penetration, minimal damage to normal tissues, precise on/off control, and rapid response. Furthermore, NIR propulsion can be integrated with other propulsion mechanisms to overcome the limitations of single-mode systems. In this review, we explore the design of NIR light-propelled NMs, categorizing their mechanisms into three types: (1) photothermal propulsion, (2) NIR light-triggered bubble propulsion, and (3) photothermal-bubble dual-driven propulsion systems. We also highlight the applications of NIR light-propelled NMs in treating diseases such as tumors, thrombosis, and bacterial infections. In addition, the challenges and future prospects for the development of NIR light-propelled NMs are also discussed.
