Mixing of samples and reagents in microchannels is a key technology in realizing a μTAS. Turbulence is not practically attainable in micro-scale since Reynolds number is extremely low. Therefore, introducing oscillations or electrical force to disturb liquid flow is necessary to enhance the mixing in microchannels. Some researchers reported mixing method by the use of time pulsating cross-flow into main channel. In those systems, complex actuators are necessary and the efficiency is not so high due to the difficulties in the optimization. In this paper, we present a simple mixing method using an asymmetric pulsating flow.
