A cell screening device including a bottom plate, a cell placement membrane, a pair of fluid injection parts, and a flow channel, the flow channel being formed between the bottom plate and the cell placement membrane and extending in such a manner that the flow channel end parts respectively reach the fluid injection parts. In the cell placement membrane, a plurality of wells, each having a size capable of housing a single cell, and through holes are formed. In the back side of each lid, i.e., the ceiling face of the flow channel end part, a debubbling surface, which rises in an inclined or step-like manner as getting closer to a fluid injection hole, is formed.

A particle capturing device including a substrate, a particle capturing film configured to capture particles, and a support configured to support the particle capturing film when tension is applied to the particle capturing film such that the particle capturing film is in parallel with the substrate and a space is formed between the particle capturing film and the substrate.

Particle capturing device and particle capturing method

A method for collecting a fine particle stored in a structure by suctioning the fine particle using a nozzle, in which, as the structure, a structure in which at least one communication portion that communicates a space storing the fine particle with one surface side and the other surface side of the structure is formed is used.

Collection method for fine particles and collection system

A filter film includes a through-hole and a recessed portion having a size capable of capturing one particle, in which the recessed portion is open to one face of the filter film, the through-hole in the one face has a shape or a size such that the one particle is not capable of passing through the through-hole, and the through-hole and the recessed portion are disposed close to each other.

Filter film and use thereof

A particle capture device includes first and second substrates. The first substrate has recessed portions that have a size capable of capturing one particle. Each recessed portion has connection holes that have a size capable of allowing a dispersion medium of particles to move therethrough. A flow path that has the connection holes as an inlet port and an end portion of a first side of the first substrate as an outlet port is defined between the first substrate and the second substrate. A total opening area of the connection holes is 1 mmor more and less than 10 mm, and a cross-sectional area of the flow path at the outlet port is 0.8 times or more the total opening area; or the total opening area is 10 mmor more and 1000 mmor less, and the cross-sectional area is 0.1 times or more the total opening area.

The purpose of the present invention is to provide: a surface treatment liquid that is capable of favorably hydrophilizing or hydrophobing surfaces of an object to be treated without having to include a film forming resin; and a surface treatment method using the surface treatment liquid. The present invention provides a surface treatment liquid which comprises (A) a resin and (C) a solvent, wherein as (A) the resin, a resin is used which has a weight average molecular weight of 100000 or more and contains a functional group I which comprises one group or more selected from the group consisting of a hydroxyl group, a cyano group, and a carboxyl group, and a functional group II which is a hydrophilic group or a hydrophobic group other than the functional group I.
