Paper Abstract

Optical trapping is a technique for the manipulation of micrometer-ordered particles, and has features of noncontact and nondestractivity, which are inherently features of the lights1, 2). The optical trapping technique was first demonstrated by Ashkin et al.1) in 1970. The technique has been initially used to manipulate biological cells and measure motor force of molecules in biological physics3,4). Recently, it has been used to extract the internal solution from trapped microcapsels by laser ablation in micorchemistory5) and to position and move micro-objects for micromachining6).
