Meet the humble “Magnetosperm,” a tiny, sperm-like robot with incredible potential in the medical world.

It’s approximately six times longer than a human sperm, and scientists at the American Institute of Physics say in a paper that Magnetosperm “technology could be used not only to help with fertilization, but also chemotherapy treatment.”

Patients who undergo chemotherapy to kill cancer cells can experience serious negative side-effects, if healthy cells are damaged in the process. Using the sperm-like robots, doctors could more accurately target the cancer cells, and could help protect healthy cells from exposure.

Because Magnetosperm was “designed to move very very small things around,” the robots could also be used to assemble any object on “nano- and micro-scales.” Scientists also speculate that magnetosperm could help improve egg fertilization.
