South Korean scientists may have found a way to remove dangerous heavy metals such as lead from blood by using specially designed magnetic receptors.

The receptors bind strongly to lead ions and can be easily removed, along with their lead cargo, using magnets, they wrote in an article in Angewandte Chemie International Edition, a leading chemistry journal.
