About: Nanoscale plasmonic motor

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

A nanoscale plasmonic motor (sometimes called a "light mill") is a type of nanomotor, converting light energy to rotational motion at nanoscale. It is constructed from pieces of gold sheet in a gammadion shape, embedded within layers of silica. When irradiated with light from a laser, the gold pieces rotate. The functioning is explained by the quantum concept of the plasmon. This type of nanomotor is much smaller than other types, and its operation can be controlled by varying the frequency of the incident light.

  • A nanoscale plasmonic motor (sometimes called a "light mill") is a type of nanomotor, converting light energy to rotational motion at nanoscale. It is constructed from pieces of gold sheet in a gammadion shape, embedded within layers of silica. When irradiated with light from a laser, the gold pieces rotate. The functioning is explained by the quantum concept of the plasmon. This type of nanomotor is much smaller than other types, and its operation can be controlled by varying the frequency of the incident light. A working demonstration model has been produced by researchers with the Lawrence Berkeley National Laboratory and the University of California, Berkeley. Likely further developments include improving strength and flexibility, and identifying lower-cost materials. Applications envisaged include unwinding the DNA of living cells, and efficiently making use of solar energy. (en)
