Researchers have developed a tube-shaped microbot that offers a cheaper and more effective way of removing heavy metals than previous methods. The self-propelled microbots use an outer layer of graphene that binds to lead ions it comes in contact with. The scientists found that they can remove 95 percent of lead from polluted water in one hour, and once they have a full payload, they can be cleaned and reused multiple times.
