A microfluidic sorting device and method employing dielectrophoresis (DEP) induced field flow separations are described herein. The microfluidic sorting device has a microchannel and an array of electrodes disposed along the microchannel. The electrodes may be oriented at an angle relative to the microchannel. Non-mammalian samples such as plant samples flow in the microchannel and through the electrode array. Current is passed through the electrodes causing a DEP force to be exerted on the samples. This force may generate a torque that causes one type of sample to rotate and slide along the electrodes, thus separating the samples by type. The separated samples are collected in different output channels
