The latest bit of brilliance from the field of robotics is a tiny micro-motor that can identify, trap, and transport individual cells. It’s a serious feat of engineering that could find uses from medicine to air purification.
Importantly, both electric and magnetic fields can control the machine – and the latter will be vital if the microscopic robot is eventually going to be deployed in the human body, which is what its inventors intend.
The bot ranges from 5 to 27 micrometers across and is made from a specially engineered polystyrene sphere coated with the conductive materials chromium, nickel, and gold.
