Research Abstract	Cancer cell capture in the blood has been studied in many ways. However, the purity of the cancer cells to be obtained is low and could not be applied in the decision of treatment and diagnosis. This study aimed to develop technologies to get the cancer cells with high purity from the blood. We investigated the recovery rate of cancer cells using an electric field non-contact stirring technique we have developed. However, it was not very good results. This technique was not able to stir the small amount of liquid uniformly. To solve this, we developed a water repellent ring to uniform the stirring. Stirring has become uniform using this ring. Study period was ended, but is continued further studied using this.
