Mag­netic sperm cell kills can­cer

In the fu­ture, doc­tors will be able to steer can­cer-killing sperm cells to can­cer tu­mours by means of a mag­net.

Science Illustrated - - SCIENCE UPDATE -

The sperm cells are placed in a liq­uid with

chemo drugs such as Dox­oru­bicin, which kills can­cer cells, but not sperm cells. The drugs en­ter the sperm cells.

The sperm cell is "dressed" in a mi­cro­scopic

"suit", which is lined with metal. The suit is at­tached to the sperm cell's head and has four arms, which func­tion as a type of an­ten­nas, reg­is­ter­ing when the sperm cell hits the can­cer tu­mour. The sperm cells are in­jected into the woman and start to swim for­wards. The doc­tor uses a mag­net out­side the body to steer the sperm cell to­wards the tu­mour. When the sperm cell col­lides with the tu­mour, the four arms at the front of the suit move aside, let­ting go of the sperm cell. The sperm cell moves in be­tween the can­cer cells, and its can­cer drugs be­gin to com­bat the can­cer tu­mour.
