Introduction Nanotechnology is now a very important field of study in most academic institutions around the world. The industry has concentrated its efforts on nanotechnology as it has shown that investment in this field is very profitable. The development of research in the area of nanotechnology requires sophisticated equipment and techniques including scanning electron microscopy transmission microscopy with accessories to achieve high resolution quantum tunneling microscopy X-ray spectroscopy of dispersion energy as well as electron diffraction of low energy. The use of nanotechnology suggests that certain fields of medicine can be a revolution specially in monitoring the disease through imaging tissue repair and control of the evolution of diseases protection and improvement of biological human systems pain relief and administration of drugs to specific cells just to refer some of the most important applications. All these applications would be new technological advances that are promoting a new era in assistencial medicine. Cancer is a leading cause of death throughout the world. Of the 58 million deaths that occurred in the world in 2005 million 13 were due to cancer. The types of cancer leading to overall mortality in humans are the lung stomach liver colon and breast. Over 70 of all cancer deaths occurred in developing countries. It is expected that the global number of deaths from cancer continue to increase throughout the world and reach 9 million in 2015 and million in 2030. Nanomedicine has shown an important growing in the war against cancer in the last two decades. Early detection is the main limitation of the current cancer treatments. Several techniques at molecular scale have been focused on early detection and treatment of the disease by identification and selective targeted of cancer cells but their applications in
