Carbon nanotube(CNT) has been recognized as a key material that drives the green innovation to generate new technology in a wide range of applications such as novel semiconductor, advanced composites, environmental materials and possible bio-applications. Present project aims especially to exploit a way to precise control of the growth and structure of double-walled(DWNT), and multi-walled CNT(MWNT), to reveal their growth mechanism, and to selectively grow desired CNT. The goal is to contribute to basic science, applications and understanding the basic toxicity aspect of CNT, from viewpoint of materials science, through an exact control of such as the microscopic structure and the electronic function. From the viewpoint of safe-nanotechnology as" Safe Innovation", the structurally controlled CNT should be pursued for promising growth of CNT science and technology
