Abstract
High through-put parallel biomolecules sorter was fabricated with the three dimensional PDMS stack structure. Three dimensional channel structure was realized by using PDMS dry etching. High speed switching of 10 ms order in each channel was realized with four and eight parallel type sorter. Sorting rate is about 20 samples/sec in the case of the four parallel type sorter. High through-put sorting of about 20 times higher than that of the previous single channel sorter was obtained in actual E. coli cells separation.
