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.

Particle capture device

A composition for optical imprint having excellent transferability of a mold shape and giving a pattern having excellent alkali resistance at high temperature by optical imprint and subsequent heating and a method for producing a pattern using the composition. The composition includes a polysiloxane including a structural unit 1 represented by Formula (a1) and a structural unit 2 represented by Formula (a2) and a polymerization initiator. The polysiloxane has a structural unit 1 content of 30% to 85% by mole and a structural unit 2 content of 15% to 70% by mole based on the entire structural units in the polysiloxane. In the formulae, Rrepresents a group containing an ethylenic double bond, and Rrepresents an aryl group having 6 to 15 carbon atoms which may have a substituent.
