Abstract: A cell isolation method includes: a cell trapping step of allowing a test liquid to pass through a cell trapping filter which has a plurality of through-holes in the thickness direction, thereby trapping isolation target cells contained in the test liquid on one surface of the cell trapping filter; a gel embedding step of introducing a stimulus-responsive hydrogel onto the one surface of the cell trapping filter on which the cells have been trapped in the cell trapping step, thereby embedding the cells in the stimulus-responsive hydrogel; a gel hardening step of applying a stimulus to the stimulus-responsive hydrogel in which the cells are embedded, thereby hardening the stimulus-responsive hydrogel; and a detachment step of detaching the stimulus-responsive hydrogel that was hardened in the gel hardening step from the cell trapping filter.

Abstract: A cell trapping device includes a housing that includes an inlet opening connected to an inlet line through which a cell dispersion liquid is introduced and an outlet opening connected to an outlet line through which the cell dispersion liquid is discharged; and a filter which is positioned within the housing and includes a trapping region for trapping cancer cells contained in the cell dispersion liquid. The filter is bonded to the housing, at least a part of the trapping region is formed of an observation region for observing the trapping region from the outside, the inlet line and the inlet opening are arranged at outer positions than the observation region when viewed from a normal line direction of the filter, and the inlet line is extended along an in-plane direction of the filter.

Abstract: An information providing apparatus includes an image capturer for capturing an image of a customer which requires a certain time to be consumed at a given location, an attribute information acquirer for estimating an attribute of the customer based on the image captured by the image capturer and acquiring attribute information representative of the estimated attribute, and a customer information output unit for outputting customer information depending on the attribute information acquired by the attribute information acquirer.

Abstract: Provided is a magnetic particle holding carrier enabling automatization of treatment of a biological substance such as a protein by improving dispersibility of nano-size magnetic particles and suppressing nonspecific adsorption onto the wall of a container such as a pipette tip without damaging the properties of the nano-size magnetic particles such as a large solid-phase area and ability to arbitrarily design a functional protein, and provide a method for preparing the same. The magnetic particle holding carrier is formed of a micro-size nonmagnetic carrier and a plurality of nano-size magnetic particles bound to the carrier.
