Could nanobots make your electronics last FOREVER?

As more of our lives are reliant upon mobile electronics, there is an ever-growing risk of their delicate circuitry being damaged by knocks and bumps. But engineers have developed swarms of tiny autonomous molecular'robots' that can repair broken circuits that are too small for the human eye to see. The technology could help to extend the life of electronics, allowing expensive mobile phones, laptops and tablets to continue working for longer. The molecular'robots' are propelled along electronic circuits until they find an area that is damaged where they congregate to restore conductivity. The nanobots mimic the platelets found in blood, sensing a wound and aggregating at that spot to'heal' the damage.
