Chapter 22: Nanotechnology in Medicine: Its Time Has Come

Nanotechnology in medicine: Its time has come Nanotechnology has been likened to a modern-day “industrial revolution” that is expected to have a major influence on industry, science, global economies, and society in general. Its presence is already felt in the miniaturization that is occurring across all fields of science. Nanotechnology has applications in a broad range of industries including electronics, materials sciences, chemical manufacturing, and pharmaceuticals. In fact, nanomedicine's time has come; at least 12 products have already been approved, and many more are in the pipeline. The term nanotechnology encompasses a spectrum of applications and products that are defined by their very small size, which is measured in nanometers (nm). The National Nanotechnology Initiative defines nanotechnology as the understanding and control of matter at dimensions of roughly 1-100 nm. This small size enables nanotech structures to interact at the atomic, molecular, and macromolecular levels. To put the nanometer size ...
