Abstract
A micro-patterned plate composed of an array of releasable elements surrounded by a gel or solid wall and methods of manufacture of the micropatterned plate. The surface properties of walls can be tailored if needed to be repellent or attracting to proteins. The walls can also inhibit cell attachment. The walls enable cells or other materials to be localized to the tops of the releasable elements. The individual element in the array of releasable elements can be released from the array by a mechanical force.
Claims8
A micropatterned plate comprising:
- a plate body,
- an array of a plurality of elevated sites extending from a surface of the plate body and releasably attached to the surface of the plate body, wherein the plurality of elevated sites are adapted to act as a carrier for biological material of interest adhered thereto when released from the surface of the plate body, wherein the plurality of elevated sites are releasable from the surface of the plate body leaving the structure of the plate body intact when one or more of the plurality of elevated sites is released from the surface of the plate body, and
- a plurality of walls separate from the plate body and extending from the surface of the plate body contiguously across the plate body in a criss-crossing configuration, wherein the plurality of walls fill cavities between each adjacent individual ones of the plurality of elevated sites in surrounding contact with individual ones of the plurality of elevated sites interposing and forming a barrier between individual ones of the plurality of elevated sites and preventing a fluid in contact with a top surface of the individual ones of the plurality of elevated sites from the cavities between each adjacent individual ones of the plurality of elevated sites, and wherein the plurality of walls are formed such that the biological material of interest adheres only to the plurality of elevated sites
- and wherein the plurality of elevated sites comprise a plurality of micro pallets.
