Carbon Nanotubes are newly discovered carbon: it is fullerene related structures but a fullerene's carbon form a sphere while a nanotube is cylindrical. According to theoretical predictions of carbon nanotubes. the tubular fullerene. may possess extraordinary physical and chemical properties. Due to its unique properties, carbon nanotubes have found a variety of potential applications in advance technologies; including nanoelectronics, biomedical, electromagnetics, electrochemical, composite. mass storage, etc. They provide an alternative to current technology to achieve better performance and smaller sizing in numerous applications. It brings technologies of all area to the edge and beyond expectation in the past. This paper will cover the outstanding properties of carbon nanotubes and the applications of carbon nanotubes
