This book describes the nanotechnology revolution that will transform human health and longevity. It opens a window onto the nanoscale-the infinitesimal realm of proteins and DNA where physics and cellular and molecular biology meet-and introduces readers to the rapidly evolving nanotechnologies that are allowing us to manipulate the very building blocks of life. The author gives an insider's perspective, revealing how nanotechnology enables a new kind of multidisciplinary science that is poised to give us control over our own biology, health, and lives. Drawing on her perspective as one of today's leading researchers in the field, she describes the exciting ways in which nanotechnology makes it possible to understand, interact with, and manipulate biology. In turn, nanotechnology is revolutionizing medicine in ways that will have profound effects on our health and longevity. The book offers insight and hope that we may all share in the benefits of this revolutionary research.
