Building skills, a two, a university professor, is explaining potential applications of nanotechnology. Listen to the lecture and complete the notes below. One key aspect of nanotechnology is that things behave in strange ways. When you reduce them down to the smallest size, certain elements like silver, gold in carbon take on super powers at small sizes. Scientists are currently using this knowledge to build faster computers and create amazing new materials. For instance, some of these materials can kill bacteria and get rid of bad smells or even detect poisoners, all thanks to these amazing effects. On the nano level, if you add a super material that detects poisonous to an ordinary material, let's say, plastic, you've created a smart material that can identify spot food. If the food goes bad, IT changes. Besides creating a number of super materials, scientists have also been busy building nano machines, one at matter time. While the technology is still Young, IT looks very promising. So what will happen in the future? Nano factories will someday be used to build bone inside the body and produce electricity for self powering devices. Larger ones will make things from food to feel anywhere in the world, and very inexpensively. Someday we will also have nano robots. Imagine a fifty nanometer wide nano ship that can enter the bloodstream and transport medicine to specific locations in the body. Other blood swimming nano robots will detect disease, repair broken parts of the body and even take pictures of our insights.
