Abstract： |
The present invention belongs to the field of near field optics and optical fliers technology. Said invented method makes laser and near field probe interact to obtain near field local intensified optical field, and utilizes said optical field to make the optical gradient force of micropracticles produce action to implement the optical pliers operations of catching, moving, extending twisting and releasing. Said invention radically breaks through the resolution and operation-control accuracy limited by diffraction of traditional optics, and makes the resolution attain subwavelength or nanometre level, and is applicable to biological single molecular operation and control. |
