Nanotechnology is the study of extremely small structures of 0.1 to 100 nm size. It is a relatively new field of science and technology. Nanotechnology represents an important scientific advancement and can contribute several benefits to human and animal health. Nanotechnology has various applications in the field of health and medicine, electronics, energy and environment. Numerous advancements in nanotechnology helps in treatment of various neuro degenerative disorders such as Parkinson’s disease, Alzheimer’s disease which are otherwise less curable by conventional medicines. Another wonder of nanoscience is nano-pharmaceuticals which detect diseases at an earlier stage. In just few years nanotechnology has shown a great progress in human and veterinary medicine. Scientists predict that such a progress in nanotechnology could represent a measure breakthrough in addressing some technical challenges faced by human and veterinary professionalists. Nanotechnology has a bright future, when merged with other technologies resulting in the emergence of new innovative hybrid technologies. Thus nanotechnology will raise our technological capabilities to another level, improving healthcare and quality of life, increase our standard of living and will drive further economic expansion into medical and veterinary profession.
