Nanotechnology
NANOTECHNOLOGY Nanotechnology is a multi-disciplinary field of applied science, technology and industry which involves creating and manipulating matter at the nanoscale. Nano means small and is the prefix used to describe properties at 10 -9 . Therefore the nanoscale exists for characteristics that form in terms of particles or channels at a nanometer that is 10 -9 or one ten-thousandth the width of a human hair. The nanotechnology revolution promises big things. Many scientists in around the world believe that nanotechnology will allow the creation of tiny machines and engines for use by humans in many different environments. One concept that has received a lot of attention in this regard is the idea of the nanobot. A robot created on the nanoscale and which could perform medical interventions in living human beings by travelling through blood vessels. Nanobots might scan for cancer cells, deliver drugs directly to sasaran organs or even repair defective body parts. As well a
