  • Patent number: 10792661
    Abstract: A device includes a first structure with a sheet layer with a plurality of discrete through-holes and a second structure coupled to the first structure. At least a portion of a first surface of the sheet layer of the first structure is exposed from the second structure. A top portion of the sheet layer, including the exposed portion of the first surface of the sheet layer, includes fluorocarbon. The second structure includes a material of a higher surface tension than the top of the sheet layer. A second surface of the sheet layer, opposite to the first surface of the sheet layer, is embedded in the second structure. The second structure extends at least partially into the plurality of discrete through-holes of the first structure.

  • Patent number: 10725020
    Abstract: The present invention provides an apparatus for conducting biological assays which employs “virtual wells” in lieu of the physical wells of conventional array plates. Also provided are methods of processing a sample and/or culturing cells using the apparatus and systems described herein. In some embodiments, the apparatus includes a first structure having a sheet layer with a plurality of discrete through holes; and a second structure coupled to the first structure, the second structure including a base layer. At least a portion of a first surface of the sheet layer of the first structure is exposed from the second structure, and a second surface of the sheet layer, opposite to the first surface of the sheet layer, is embedded in the base layer of the second structure adjacent the first surface of the base layer.

  • Patent number: 10632468
    Abstract: An apparatus configured for improving retention of non-adherent cells is disclosed. The apparatus includes a plate that includes a number of elements having a first surface energy arranged in an array with an overlay, on the plate, having a second surface energy. The first surface energy results in a hydrophilic surface and the second surface energy results in a hydrophobic surface. A diameter of the elements is at least 1 mm. A height of the overlay having the second surface energy, which results in a hydrophobic surface, is between 5% and 100% of the diameter of the elements. The apparatus also includes a wall circumferential to the plate. A method for performing multiple reactions with the apparatus is also disclosed.

  • Patent number: 9878328
    Abstract: This describes an apparatus comprising a plate with a number of elements having a hydrophilic surface arranged in an array with an overlay having a hydrophobic surface. A height of the overlay is between about 5% and 100% of the diameter of the elements. The application also discloses a wall circumferential to the plate; and a removable grid insertable into the apparatus, said grid comprising dividers enclosing a number of through-holes, said through-holes spaced in the grid to allow alignment of the through-holes of the grid over the elements in the plate when said grid is inserted into the apparatus, said dividers of the grid inserted into the apparatus form sides of wells bottomed by the plate and at least one element on said plate.
