	Nanomotor - ArticleWorld
		A nanomotor is a nanotechnology-based device, operating at a molecular level, and which is capable of effecting forces of the order of piconewtons.
		These molecular motors, or ‘nanomotors’ as they are dubbed, can be implanted in artificial devices to perform much the same functions that their living-cell counterparts perform.
		Factors that affect movement speeds of nanomotors include the torque magnitude involved and the viscosity of the surrounding medium.

	Nanomotor Made From Single DNA Molecule Is A First
		While it is not the first such DNA motor, Tan said his nanomotor is the first to be built from a single molecule rather than several different DNA molecules.
		Tan said it is difficult to predict when nanomotors, whether built from single or multiple molecules, will reach the stage that they can be used along with a drug or clinical treatment.
		He said the next step in his research is to coax his nanomotor to move a tiny particle from one place to another, demonstrating that it can perform a potentially useful task.

		Called a "synthetic rotational nanomotor," this device was constructed under the leadership of physicist Alex Zettl, who holds a joint appointment with Berkeley Lab's Materials Sciences Division and the University of California's Berkeley campus.
		The first nanomotor Zettl and his colleagues built consisted of a gold paddle-shaped rotor blade, measuring between 100 and 300 nanometers in length, that was connected to a carbon nanotube shaft less than 10 nanometers thick.
		The synthetic rotational nanomotor has been clocked at 33,000 cycles per second and is believed capable of speeds approaching one billion rotations per second.

Such devices, for example, could be injected in addition to drugs intended to treat cancer cells or tumors, according to Tan.

	Optical Physics (Site not responding. Last check: 2007-10-31)
		We have successfully produced a light-driven nanomotor that uses optical tweezers to trap glass nanorods.
		When moved away from a surface, the motion is nonlinear with interesting behavior once the nanomotor is driven above a critical frequency determined by the particle polarizability, the light intensity, and the viscosity of the surrounding medium.
		Another area of interest is the use of light and novel techniques, such as single-molecule detection, optical tweezers, and total-internal reflection to investigate and understand the operation of biological motors.
