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 (纳米技术) 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 nanobots (纳米 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 forever 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.
