Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic
Advanced Robotics Research, EarlyView.Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these
