These days, nanotechnology is used primarily to make things stronger, stiffer,
and smoother. Due to their tiny size, nanoparticles increase the overall surface a
of an object, and that acts to give the object special properties
However, nanotechnology is also used in the field of biochemistry. One possible
of nanotechnology in the future is in the field of robotics. It might be feasible for tiny
nano-robots, or "nanobots," to be produced that could easily perform tasks in a very
small scale. Each of these nanobots would be so small that you would need a special
microscope to see them. Because of their small size, however, a great deal of them

furod One drawback to nanotechnology is that the structures are so small that they pose
some health and environmental risks. Because of their size, they can float around in
the air and enter our lungs without our knowing about it. The effects of this are not yet
known, but in the future, if the use of this sort of technology becomes more common,
some specialists believe that we may suffer from various illnesses. Regardless of the
risks, however, it seems that nanotechnology is something that will be with us for a
long time.

capable的意思應該是「有能力的」，例如Tom會打棒球可以說Tom is capable of playing baseball.但是feasible跟practicable是可以實行的，例如這個計畫可以實行就是This plan is feasible/practicable.
