Nano-motors: now faster than ever!

Do you need a motor the size of a large molecule?

Now scientists in Arizona have customized nanoengines by spiking the gas with rocket fuel and adding carbon nanotubes to strengthen the motor's micro-sized frame.

The new additions revved up the tiny motors to 20 times faster than existing nanomotors.

Although any real-world applications are still years away, Wang and his fellow researchers are trying to adapt the powerful nanomotors for use inside the body and for environmental remediation.

If a hazardous chemical is released into the environment, nanomotors could use them as fuel to power themselves. As they move through the contaminate they spit harmless chemicals out of their nanotailpipes.

In the body, drugs work by passively diffusing through the body until they literally run into their target, whether that target is a tumor or a invading pathogen.
