Cellular cargo manipulation using magnetically steerable microrobots in dense environments.

This study presents a microrobotic system that utilizes magnetic Janus microrobots and a 3D-printed magnetic tweezers setup controlled by electromagnetic coils to transport cells in a densely crowded environment. The system was successfully demonstrated to transport cells in a densely populated sample of cells. The results indicate that this microrobotic system could address challenges such as off-target delivery, thereby realizing the full potential of medical microrobots for this and other applications. This study represents an important step towards developing a more efficient and effective method for targeted drug delivery in the field of medicine.
