Imagine a doctor who performs surgery so precisely that she removes individual cancerous cells one at a time. Miniature robots could make this kind of accuracy possible. We’ve heard about tiny robots for medical use in the past, but the technology is still rudimentary.

Now, researchers at North Carolina State University and Duke University have demonstrated that they can program tiny machines to capture and transport single cells.
