      Imagine this: a television screen has the size and thickness of a piece of paper. You carry it around in
your pocket and take it out when you want to watch a show. Imagine a guitar so tiny that you can't see it
with the human eye, but you can hear sound when its strings are pulled.
      Nanotechnology (纲米技术)  is the science that deals with doing things in a very small way, and it is
being studied and developed all over the world. Many scientists say nanotechnology will produce the next
industrial revolution (工业革命) .
      Perhaps nanotechnology will have the biggest influence on medical science. Imagine manobots (纲米机器人) in medicine. Thousands or even millions of tiny machines can be sent into the human body with
specific tasks. For example, they can be designed to find and destroy cancer cells or viruses (病毒). Other machines may stay in the human body for ever to help organs (器官) that are not working properly.
      When could all of these happen? Scientists predict that most of these are possible in the next 30 years. Thousands of scientists around the world are working on these micro - machines.  Nanotechnology is just around the corner.
