“…Mizuno et al [26] have first demonstrated the ET vortices induced by a strong infrared (IR) laser source and applied to transport DNA molecules in 1995. Although they have also simultaneously applied an optical field and an electrical field to manipulate particles and molecules [27][28][29], those works are not included in this paper since two fields independently worked for different purposes in those studies: an optical force for trapping, positioning, or cutting; and an electrostatic force for rotating or extracting.…”

This paper presents optoelectrofluidic technologies for manipulation of nanoparticles and biomolecules. Optoelectrofluidics provides an elegant scheme for the programmable manipulation of particles or fluids in microenvironments based on optically induced electrokinetics. Recent progress on the optoelectrofluidic manipulation of nanoobjects, which include nanospheres, nanowires, nanotubes, and biomolecules, is introduced. Some potential applications of the optoelectrofluidic nanoparticle manipulation, such as nanoparticles separation, nanostructures manufacturing, molecular physics, and clinical diagnostics, and their future directions are also discussed.

This paper presents the optoelectrostatic micromanipulation (OEMM) of single cell / DNA molecule. Single cell is trapped at the center of a microscope field by optical pressure and is oriented along the electric field lines b y electrostatic force. Precise measurement of shape or electrical properties of individual cell can be made by this technique. Using a rotating electric field, a cell can be rotated. The frequency dependence of rotational characteristics may be utilized to determine its viability. The OEMM is also applied in manipulation of single DNA molecule. The molecule can be trapped optically and stretched using flow and/or electrophoretic force. The fragments are cut from a stretched DNA molecule, and are recovered successively. Using this procedure, fragments of the single DNA molecule can be prepared without loss of the order information.This technique may contribute to enhance speed of DNA sequencing.
