Fractionating apparatus having colonies of pillars arranged in migration passage at interval and process for fabricating pillars |
摘要 |
A fractionating apparatus is used for fractionating sample into micro-structures different in size, and includes a fractionating unit formed with a fractionating passage; the fractionating passage is defined in a groove formed in a substrate of the fractionating unit, and pillar patches are formed in the groove at intervals wider than the gap among the pillar patches; while the sample is migrated through the fractionating passage, small-sized DNA molecules are trapped in the pillar patches, and large-sized DNA molecules are smoothly migrated through the wide intervals; this results in that the large-sized DNA molecules reaches the end of the fractionating passage faster than the small-sized DNA molecules without clogging.
