Abstract

A fast buoyant flow occurs along the gap between electrodes aligned in the vertical direction in a microchannel filled with isotonic saline. A micropump and a micromixer have been realized by applying this phenomenon in two types of device: an upright chip and a horizontally oriented upright chip, respectively. These devices have very simple structures and can be made from cheap materials by uncomplicated manufacturing processes. Because the devices work efficiently in the range of solution conductivities that includes isotonic saline, we expect them to be useful in biochemical assays and medical tests.
