"stem cells are used to replace cells damaged by chemotherapy or diseases... need to be applied directly to the damaged area or to the closest region to maximize the efficacy of therapy... developing a magnetically powered stem cell-based microrobot... were able to engraft cellbots onto the cerebral cortex of a rat... potential to become a key player in the treatment of neurological disorders such as brain cancer, Parkinson's disease and Alzheimer's disease"
