Abstract

In order to separate a particular type of cell from a mixture of several different types and different morphologies of cell samples, a microfluidic particle sorter based on optical tweezers array system is used. By using a galvanometer scanning system and a laser modulation device to the optical tweezers array system based on double-plate shearing interferometers, the particles, such as cells, can be trapped and move to be separated. Experimental results show that this device can be successfully applied to capturing and moving particles.
