Researchers create slimy, magnetic ‘soft robot’

Researchers at The Chinese University of Hong Kong have created a “soft robot” made of mucus that contains magnetic particles, which can be manipulated using external magnets.

The magnetic particles are toxic, but have theoretically been made safe to enter the human body after being covered with a layer of silicone compound – although further safety tests will be needed in the future.

The Hong Kong team hopes that one day the slime will be used to collect items that have been accidentally swallowed.
