The use of diffractive optical elements (DOEs) for multiple trapping of dielectric micro-spheres immersed in a fluid has been demonstrated recently. When the DOEs are implemented on a spatial light modulator (SLM), the trapped particles can be independently moved by changing the configuration of the DOE. In this paper we demonstrate phase DOEs implemented on an optical addressable SLM to move an array of trapped particles in a volume of about 20x20x6 μm. Experimental results show the usefulness of this technique for particle micromanipulation in biology.
