The Material World

BBC Radio 4
on BBC Radio 4 FM

Tiny magnetic particles that store huge amounts of data are essential to video, audio and computer technologies but now magnets on a nano scale could revolutionise medicine. By attaching magnetic particles to drugs, they can be guided to exactly where needed in the body. How do you make these perfectly engineered nano-scale magnets? Quentin Cooper talks to Professor Andrew Harrison from Edinburgh University, who is farming bacteria to make these particles for us. He also talks to Professor Jon Dobson from Keele
University to find out why finding microscopic magnets on meteorites could be signs of life from Mars. Producer Pamela Rutherford
