A device for preparing a glass slide specimen of cells has: a filter that has recesses, which capture target cells that are at least one of circulating tumor cells within blood or rare tumor cells within a body fluid, and pores that are formed in the recesses and that pass non-target cells therethrough; a glass slide that is superposed onto a surface of the filter, at a side at which the target cells are captured, and onto which the target cells are transferred; a cover member that is placed on a surface of the filter at a side opposite from the glass slide, and that seals in a buffer solution for immersing the target cells at interiors of the recesses; and a container into which the glass slide is immersed and in which is stored a preservation liquid that preserves the target cells that have been transferred onto the glass slide.

A device for isolating periphery circulating tumor cells or rare cells includes a metal filter having depressions that can capture periphery circulating tumor cells or rare cells that are in a body fluid, and pores that are formed at the depressions and that can pass therethrough body fluid cells other than periphery circulating tumor cells or rare cells.

Provided is a microchannel chip, for microparticle separation, which can continuously separate microparticles, from a solution in which microparticles of different particle diameter are mixed, without needing to use an antibody or similar, and without causing clogging. Also provided are a microparticle separation method and a system for microparticle separation using the chip. Microparticles can be captured by using the microchannel chip for microparticle separation, the microchannel chip being characterised by being provided with a plurality of main channels and capture portions that are wider than the main channels and at least one of which is provided to each main channel.
