MICROPARTICLE SEPARATION CHIP, AND MICROPARTICLE SEPARATION SYSTEM AND MICROPARTICLE SEPARATION METHOD WHICH EMPLOY SAID MICROPARTICLE SEPARATION CHIP

摘要

Provided is a microparticle separation chip capable of continuously separating microparticles from a solution in a short period of time in which microparticles having different particle diameters are mixed, without the need to use antibodies or the like. Also provided are a microparticle separation system and method for microparticle separation using the chip. The microparticle separation chip comprises a substrate and at least three or more pillars, a single capture site for capturing to-be-captured microparticles being formed using the at least three or more pillars having one end provided on the substrate and the other end open above, the spacing Z between any mutually adjacent pillars that form the single capture site being Y < Z ‰¤ X, where X is the size of the to-be-captured microparticles, and Y is the size of the microparticles to be removed, and the at least three or more pillars that form a single capture site being arranged in a positional relationship in which to-be-captured microparticles captured in the capture site do not flow out from between any adjacent pillars.
