Laterally-displaced micropost array chip and use thereof

Abstract

The disclosure provides a laterally-displaced micropost array chip and the use thereof. The laterally-displaced micropost array chip includes laterally-displaced micro-pillar arrays arranged in columns or in rows. Micropost units in each subsequent column or subsequent row are displaced relative to a previous column or previous row according to a certain angle. Each of the micropost units is internally provided with one or more channels. In the one or more channels, the opening direction of at least one channel is different from the displacement directions of the laterally-displaced micropost arrays. The laterally-displaced micropost array chip of the invention more accurately separates particles of various sizes in fluids, has the function of filtering particles of small sizes, thereby enabling particles of large sizes to have an enrichment effect before entering the next array, reduces the critical separation sizes of micropost arrays, and is higher in throughput and larger in separation volume.
