How Is Nanotech Different From Biotech?
Based on the definition of nanotech given above, biotech can be thought of as a subset of nanotech - "nature's nanotechnology." Biotech uses the molecular structures, devices, and systems found in plants and animals to create new molecular products. Nanotech is more general, not being limited to existing natural structures, devices, and systems, and instead designing and building new, non-biological ones. These can be quite different: harder, stronger, tougher, and able to survive a dry or hot environment, unlike biology. For example, nanotech products can be used to build an automobile or spacecraft.
