Plasmonic Brownian Ratchet
Here we present a Brownian ratchet based on plasmonic interactions. by periodically turning on and off a laser beam that illuminates a periodic array of plasmonic nanostructures with broken spatial symmetry, the random thermal motion of a subwavelength dielectric bead is rectified into one direction. by means of the molecular dynamics technique we show a statistical directed drift in particle flow. © 2013 American Physical Society.
