Tiny robots that can transport individual neurons and connect them to form active neural circuits could help us study brain disorders such as Alzheimer’s disease.

The robots, which were developed by Hongsoo Choi at the Daegu Gyeongbuk Institute of Science and Technology in South Korea and his colleagues, are 300 micrometres long and 95 micrometre wide. They are made from a polymer coated with nickel and titanium and their movement can be controlled with external magnetic fields.
