Abstract: A method for automated cell enrichment preparation where biological cells are injected into a first subchamber and flowed through the first subchamber, through a large pore filter and into a second subchamber so that the large pore filter retains particles large particles in the first subchamber, while the biological cells pass through the first filter into the second subchamber and are retained by a small pore filter. After clearing, the biological cells are stained. A solvent exchange leaves the biological cells in solvent and they are released into a concentration module where a portion of the solvent is removed to form an enriched concentrated cell suspension.

Abstract: An apparatus and method for automated cell preparation is described. A biological cell sample, including large particles and smaller objects of interest, is introduced into a first chamber. The large particles are trapped in the first chamber using a first filter, while smaller objects-of-interest and small particles pass through the first filter into the second chamber where the objects-of-interest are trapped by a second filter having a smaller pore size than the first filter and the small particles pass through the second filter if they are smaller than the objects-of-interest. Debris is purged from the first chamber while the objects-of-interest are trapped in the second chamber. The objects-of-interest are dispensed from the second chamber.

Abstract: The present invention provides a method for embedding particles in a solid structure including the steps of extruding a slurry of particles and a polymeric solution into a linear polymer medium having particles embedded into a polymer portion; and curing the polymer portion of the linear polymer medium.
