Nanotechnology: the revolution of the big future with tiny medicine.

The historically unprecedented developments of nanoscience and nanotechnology (NT) promise to revolutionize the diagnosis, treatment and prevention of disease and traumatic injury, to relieve pain, and to preserve and improve human health, using molecular tools and molecular knowledge of the body. This article focuses on what is known as nanomedicine, referring to a definition of NT, its historical overview and developments as well as its application to medicine. In revolutionizing the manufacturing process to a nanoscale, NT promises to resolve the problems currently faced by the human race. However, in embracing this panacea, its implications, particularly within health care, cannot be ignored. This article, therefore, provides a thought-provoking consideration of how NT is likely to impact on nursing, together with the issues likely to be encountered during the care delivery process. Finally, some of the ethical questions nurses need to debate has been raised.
