Nanomedicine will employ molecular machine systems to address medical problems, and will improve human health at the molecular scale. Nanomedicine will have extraordinary and far-reaching implications for the medical profession, for the definition of disease, for the diagnosis and treatment of medical conditions including aging, for our very personal relationships with our own bodies, and ultimately for the improvement and extension of natural human biological structure and function. For example, in 1991 K. Eric. Trees become lumber, then houses. Mountains become rubble, then molten iron, then steel, then cars.
Sand becomes a purified gas, then silicon, then chips.
And so it goes. To make wood and leaves, they neither cut, stir, bake, spray, etch, nor grind. Instead, they gather solar energy using molecular electronic devices, the photosynthetic reaction centers of chloroplasts. They use that energy to drive molecular machines active devices with moving parts of precise, molecular structure which process carbon dioxide and water into oxygen and molecular building blocks. They use other molecular machines to join these molecular building blocks to form roots, trunks, branches, twigs, solar collectors, and more molecular machinery.
