什么是纳米技术?
从 国家纳米技术倡议纳米技术是对大约1到100纳米之间的物质的理解和控制。, 当处理大块材料甚至单个原子或分子时，独特的现象使新应用不可行. 一纳米是一米的十亿分之一. 一张纸大约100张,000 nanometers thick; a single gold atom is about a third of a nanometer in diameter.
Researchers seeking to understand the fundamentals of properties at the nanoscale call their work nanoscience; those focused on effective use of the properties call their work nano工程.
涵盖纳米尺度科学, 工程, 和技术, 纳米技术涉及成像, 测量, 建模, 以及在纳米尺度上操控物质.
