Tiny robots could roam inside our bodies, delivering drugs with unprecedented precision…
We’re not there yet, but we’re getting close. Last month scientists from China’s National Center for Nanoscience and Technology (NCNT) and Arizona State University said they had developed robots a few hundred nanometers across — there are 25 million nanometers in an inch — and when they injected them into the bloodstream of mice, the nanorobots could shrink tumors by blocking their blood supply.
