Well physically they are tiny radios that are built out of a single carbon nano-tube. This may sound complicated, and the science behind it is. What makes these devices special is that the key circuitry behind it is a single carbon nano-tube, so basically it is tiny.
Nano Radios were also named as one of the top 10 emerging technologies by an MIT magazine "Technology Review" (Click HERE for entire article) this past year.
This is because the effects they can have on our society are huge. Anywhere from improving our cellphones to medical diagnostic systems. They can also be used in computer's, with these radios, about the size of bacteria, attached to microchips, it would allow them communicate wirelessly. Below is an image of how these nanoradio's function.
