Systems and method for versatile multiplexed spinning/rotating bioassays are provided. This bioassay platform can take the advantage of the high-speed spinning motion, which naturally provides on-the-fly cellular imaging at the rate that cannot be reached by the conventional cameras or laser-scanning techniques, but ultrafast imaging modalities. More importantly, the functionalized solid substrates derived from the disk substrate can be compatible with adherent cell culture as well as biochemically-specific cell-capture, which can now be assayed with ultrafast imaging modalities at an ultra-high-speed line-scan rate of >10 MHz. Large-format spinning high-throughput imaging assay could thus be a potent tool for scaling both the assay throughput as well as content/multiplexity as demanded in many applications, e.g. drug discovery, and rare cancer cell screening.

A system for testing properties of a sample, the system including a test cell. The test cell includes a cell casing having a first end piece, a second end piece, and at least one wall extending between the first end piece and the second end piece. The cell casing defines a pressure boundary enclosing an interior region of the cell. The test cell further includes a sample chamber, a first reservoir, and a second reservoir disposed within the pressure boundary. The sample chamber defines an interior region. The first reservoir fluidly connects to the interior region of the sample chamber. The second reservoir fluidly connects to the interior region of the sample chamber. The test cell also has a piston assembly having a piston fluid chamber and a piston with a stem extending into the piston fluid chamber. The piston partially defines the sample chamber.

Fluid processing assemblies and methods are provided for mononuclear cell collection. Mononuclear cells are separated from red blood cells in a blood separation chamber, with the mononuclear cells and then the red blood cells exiting the chamber via an outlet port.
