Acoustophoretic devices for separating particles from a non-flowing host fluid are disclosed. The devices include a substantially acoustically transparent container and a separation unit, with the container being placed within the separation unit. An ultrasonic transducer in the separation unit creates a planar or multi-dimensional acoustic standing wave within the container, trapping particles disposed within the non-flowing fluid and causing them to coalesce or agglomerate, then separate due to buoyancy or gravity forces.

Devices, systems, and methods for separating cells or vesicles using a thermo-acoustophoretic approach are provided. A microfluidic device can be used for stiffness-based separation of cells or vesicles that otherwise have the same or approximately the same size, shape, and charge, where at least some of the membranes or vesicles have different compositions. The separation can be done by tuning the temperature of the cells or vesicles.

An apparatus for collecting or culturing cells or cell colonies includes: a common substrate formed from a flexible resilient polymeric material and having a plurality of wells formed therein; and a plurality of rigid cell carriers releasably connected to said common substrate, with said carriers arranged in the form of an array, and with each of the carriers resiliently received in one of the wells. A method of collecting or culturing cells or cell colonies with such an apparatus is carried out by depositing a liquid media carrying cells on the apparatus so that said cells settle on or adhere to said the carriers; and then (c) releasing at least one selected carrier having said cells thereon by gradual application of release energy to each carrier from the cavity in which it is received (e.g., by pushing with a probe).

A separation device for separating a solid separation target contained in a suspension obtained by suspension culture of adherent cells by using a fine scaffold material, and a separation method. The separation device has a separation chamber having a first chamber and a second chamber, and the first chamber and the second chamber are divided by a mesh structure for separation. The mesh structure for separation has mesh-holes with a predetermined size to suppress passage of the separation target, and a mesh structure for separation is configured in the separation chamber such that the liquid in the aforementioned suspension has a vertically upward directional component in the advancing direction of the liquid when the liquid passes through the mesh-holes.

A cell adhesion composition according to one aspect of the present invention comprises: an amphiphilic compound; and a conjugate of a DNA and a hydrophilic molecule, wherein the amphiphilic compound has a hydrophobic group that can non-covalently bond to a cell membrane, and a hydrophilic group, and wherein a weight-average molecular weight of the hydrophilic molecule of the conjugate is larger than a weight-average molecular weight of a hydrophilic molecule from which the hydrophilic group of the amphiphilic compound derives. According to such a cell adhesion composition, it is possible to impart a cell adhesion ability to a base material at an arbitrary timing by using light having an arbitrary wavelength.
