Nanomedicine, a scientific branch of nanotechnology that operates on the same scale as biology, offers the possibility of influencing the healing process from inside of the body by manipulating the matter at cellular or molecular levels. Throughout this book, current healing approaches based on this revolutionary new technology are summarized from a scientific assessment. The aim of the authors is to give, through select examples, a deep insight to nanotechnology status and the great progress that its rigorous application will bring to human health. The authors' commitment is to broaden the vision of health professionals who will eventually be the future users of this knowledge.
