Paper Abstract

Optical tweezer is a powerful tool for manipulating samples under a microscope. However, this technique is limited to transparent objects because it has been believed that it is the light refraction that play a significant role to manipulate the microscopic objects. We took notice of a optical force generated by a surface diffraction wave, so called creeping wave [1] , and found that it can be applicable to trap metallic objects [21. In this presentation, we show that gold Mie particles (0.5 - 3.0 im in diameter) can be trapped optically in two dimensions.
