Nano-sized devices and robots that could be deployed inside the body to deliver medicine or clear out cholesterol would make medical treatment faster and more effective. The challenge is to deliver the devices to the right spot in the body. That would require a nano-sized propulsion system — and now that’s in the realm of the possible.
Researchers from the Technion and from two German institutions have come up with a nano-sized propeller that could, when attached to a device, make its way through the viscous materials that make up the human body, like blood and fat.
