Larry Hench, Profesor of Ceramic Materials at Imperial College, London, invented the first man-made material that can bond with living tisue. 'Bio-glas' is a porous glas that can be cast in any shape, forming a scaffold for new bone cells to grow on. When bio-glas disolves, it releases substances that act like fertilisers, encouraging cells to fill the cast. This photograph shows a laboratory technician pouring a bio-glas foam into a mould prior to baking; the baking removes all liquid and forms a glasy scaffold.
