Abstract :
Summary form only given. Optical trapping of micron-size dielectric microspheres using a single beam gradient force was first demonstrated by Ashkin in 1986. Since then, extensive research and development of this technique have turned it into a practical device (known as optical tweezers), which has been used in a wide variety of biological and biomedical applications. In this paper, we report the first experimental observation, we believe, of trapping and manipulation of dielectric particles by a set of two-beam interference fringes.
