How about a motor, a million times smaller than a needle tip?
Enter the nanomotor, a motor that actually measures a million times smaller than a needle tip and a motor that can actually get some work done, in the tiniest quantities though. Researchers at the UAB research park have now combined two nanotubes to create the world's first thermal nanomotor. This nanomotor has a larger carbon nanotube as the nano-transporter and a smaller carbon nanotube which acts a rotor. Temperature changes make it possible for the smaller nanotube to rotate. That is, the smaller nanotube rotates by moving towards the colder area from the warmer area. This can be used to move materials in our human body just like the enzymes do, thus having almost unlimited applications in bio-medicine. With a motor of this scale, scientists are fast moving towards creating newer ways to treat incurable diseases and make life a lot safer. The future looks very promising indeed.
