Paper Abstract

Gold nanoparticles have very unique physical, chemical and biological characters, which makes them have widespread applications in many fields. Sorting gold nanoparticles with different size is of great importance because the unique properties of gold nanoparticles relate with their sizes extremely close. Optical sorting is an excellent way due to much better sorting precision compared with the traditional sorting methods. In this paper, a new chip design sorting gold nanoparticles is presented and results of sorting two different nanoparticles have been analyzed as well. Mie theory is used to calculate the optical force of nanoparticles in different diameter, and finite element analysis is used to analysis the variation of flow field and sorting process of gold nanoparticles.
