US scientists have customised nanoengines by spiking the gas with rocket fuel and adding carbon nanotubes to strengthen the motor's microsized frame.
Some people customise their cars by adding fuel-injection systems and extra-strong alloys. Now scientists have done the same with nanomotors, albeit on a tiny scale
They say the new additions rev up the tiny motors to 20 times faster than existing nanomotors.
A nanomachine is a tiny device less than a millionth of a metre in size that scientists hope to use in a variety of medical and research applications
The Arizona team says the powerful nanomotors could one day deliver disease-fighting drugs inside the body to invading pathogens or tumour cells, or help clean up environmental toxins by using the toxins as fuel
