With all the research going on in Nano-technology you knew that theses scientist had to be making a nano-mess. So now some of these same scientists have invented a nano-brush to clean up their nano-mess. Pulickel Ajayan and his research group centered at Rensselaer Polytechnic Institute created these nano-brushes from carbon nano-tubes. The brushes have bristles a thousand times finer than a human hair. The group invisions uses ranging from brushes for electric motors to various medical applications. So you think you have pushed technology as far as you can in your products? Think again!
