Leukemia is a disease which is diagnosed by blood test following symptom onset. The patients are often transported to a hospital after they get into serious symptom. An existing automatic blood cell counter can detect leukemia cells, only when the withdrawn blood includes many ones. However it exhibits low reliability. Therefore, the visual observation method has been still adopted to the blood test today. But this method takes time and a lot of troubles, furthermore, it needs three years at least to acquire knowledge and technique. Thus we need an automatic blood cell counter which can detect a small amount of leukemia cells in the blood of patients before disease development. In this research, we employ the dielectrophoresis to solve this problem. We successfully measured the dielectrophoretic forces generated on normal leukocytes in uniform electric field. And leukocyte and erythrocyte were separated by dielectrophoresis. Furthermore, separation of leukemia cells and normal leukocyte could be successfully achieved.
