Abstract

In this paper, a novel optical microparticle sorting method is developed by utilizing the evanescent wave in an optofluidic waveguide. Two different laminar liquid flows are injected into an optofluidic channel to form a liquid-liquid interface. Evanescent wave is generated due to the total internal reflection by applying an illumination light at the critical angle. Due to the optical forces exerted on them, microparticles with different sizes and refractive indices in the field can be efficiently sorted by controlling the flow rate and the laser power. This optofluidic device has a great potential in cell and molecule detection and sorting.
