Tiny self-propelling submarines could help clean up toxic waste

Submarines ‘re going microscopic. Tiny tubes about 10 micrometres long can propel themselves only using sunlight and will be steered by magnetic fields. These microrobots could possibly be useful for cleaning up toxic waste.

Most swimming microrobots can only move in two dimensions: according to their weight, they either sink to underneath of a liquid or float near to the surface because they swim around. Martin Pumera at the University of Chemistry and Technology in the Czech Republic and his …
