Cells, gels and DNA strands are the 'wetware' of the twenty-first century. Imagine taking cells from a cancer patient and programming them to detect disease and then prompt the body to cure itself. Or clothes woven with microchips, nanofibres and living cells to form wearable bio-weapons detection systems. Both of these revolutionary applications are closer than we think. Some scientists are pushing the boundaries even further by creating synthetic biology where brand new creatures are engineered in the laboratory. In this breathtaking book, a leading expert in the field reveals just how the stuff of science fiction is rapidly becoming a reality. This new technology will change the way we think - not just about computers, but about the nature of life itself.
