Profesor Larry Hench demonstrating 'bio-glas' in the Antenna Gallery, Wellcome Wing, Science Museum, London, May 2001. 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.
