Paper Abstract

We present an optical conveyor belt that provides trapping and subsequent precise delivery of several sub-micron particles over a distance of tens of micrometers. This tool is based on a standing wave (SW) created from two counter-propagating evanescent beams where the phase of one of the beams can be changed. Therefore, the whole structure of SW nodes and antinodes moves and deliver confined microobjects to specific regions. Based on the theoretical calculations we confirm experimentally that certain sizes of polymer particles can be more easily delivered but other sizes do not feel the SW motion at all.
