Optical manipulation provides a non-invasive, dynamic, and reconfigurable method of trapping, transporting, and sorting cells and other bioparticles. Optoelectronic tweezers (OET) enables optically-controlled cellular manipulation at much lower optical power densities than conventional optical tweezers. This enables the use of direct imaging and incoherent light to create a large (1.3 mm x 1.3 mm) manipulation area for the parallel processing of cells, microparticles, and nanoparticles. The use of direct image-actuated OET allows single-particle control for biological research and microparticle assembly.
