Abstract

Nanotechnology is the 21st century cutting-edge high-tech one, in the national economy and the technology has broad application prospects. Who mastered the nano-technology, who will be made in economic development initiatives, and continuously improve its international status. How to better development of nano-science and technology, the 21st century will be the hot topic of concern as well as scientific and technological development among the forefront of research.This paper introduces the meaning of nano-science and technology, and have a simple analysis about the reason of development of nanometer technology.The paper also discusses the nano-technology application in all fields and introduces the present situation and development of nanometer technology trends. From the research progress of perspective, nano-technology goes to all fields, it has wide application prospects.

Key words: nano-technology； development trends； application
