Nano medicine offers the prospect of powerful new tool for monitoring, repair, construction and treatment of human diseases and the improvement of human biological system using molecular nanotechnology. Changes in human behavior and life style over the last century have resulted in a dramatic increase in the diseases world-wide. Among the numerous conditions which can do harm to the human, the most fundamental problem may be due to lack of perfusion of oxygen to the tissue and blood borne pathogens. Insufficient oxygenation can lead to anemia, heart attack and sudden loss of blood supply. To overcome this, one of novel therapeutic technological concept in nanomedicine includes the application of respirocytes and microbivores to treat such conditions in humans
