Nanomotors controlled with laser light – Phys.org

Researchers from the Institute of Industrial Science, the University of Tokyo (UTokyo-IIS) have designed novel linear nanomotors that can be moved in controlled directions using light. This work opens the way for new microfluidics, including lab-on-a-chip systems with optically actuated pumps and valves.
The world of nanoscale machines looks very different to the one containing the contraptions to which we have become accustomed. For example, powering and precisely controlling a motor smaller than…
