Randomized trial uncovers enhanced therapeutic efficacy of nanorobotics in nonhuman primates, suggesting new avenues for CNS treatment.

This research aimed to develop a nanorobotic platform for improved navigation in the spinal canal for CNS therapy.
Developed an adaptive magnetic nanorobotic platform for spinal canal navigation in mice and nonhuman primates.
Implemented multiple swarm mobility modes (chain-like, vortex-like, ribbon-like) with a focus on vortex swarm as the optimal strategy.
Used a robotic arm-generated magnetic field to enhance navigation and drug accumulation at CNS target sites.
Vortex swarms improved therapeutic efficacy with enhanced drug accumulation and prolonged retention at target sites.
Demonstrated significant navigation capabilities over centimeter distances within the spinal canal.
Nanorobot migration effectively circumvented anatomical constraints at the cauda equina interface.
