Baojun Li and coworkers at Sun Yat-Sen University in China have used counter-propagating laser beams in an optical nanofibre to control the transport of nanoparticles in two opposite directions. They were also able to stop the nanoparticles where they wanted.
Being able to transport and position such particles accurately is important for various applications, for example in biomedical research and chemical analysis.
