We are developing a method to manipulate the motion of colloidal semiconductor quantum dots in room temperature liquids. In a previous study, we confirmed that CdSe/ZnS quantum dots were trapped near the electric field maximum position under optical excitation, but the influence of convection was suggested, so in this study, we attempted to improve these by making the sample solution flow and applying a higher voltage. In this presentation, we will report on the experimental results and issues.
