US developed the world's first nano-light drive motor

Release date: 2010-08-02

The US Department of Energy (DOE) Lawrence Berkeley National Laboratory and Berkeley, announced the successful development of the world's first Nano-sized Light Mill Motor. Scientists responsible for research and development said that the motor can be controlled by the frequency of light waves and can be used to create clean energy, biomedical and other fields.
Xiang Zhang, the Chinese director of the Berkeley Nano Science Engineering Center, who led the research, pointed out that the light-controlled motor is very small, only 100 units of nanometer, but the power generated is enough to drive 4000. Large silicon disk. And the study found that through different lengths of spectrum, it is easy to control the speed and direction of motor rotation, thus creating faster rotation speed or greater power.
Zhang Xiang said that the advanced technology of this technology is to greatly reduce the size of the motor. It can be used in a wide range of applications, including nano electro mechanical systems (NEMS), nanoscale solar light harvesters, and even micro-robot control systems for the testing of biological cells and DNA molecules. the study.
