A bioreactor including a bioreactor body, wherein the bioreactor body includes a first substrate and an opposing second substrate, a pathway extending through the bioreactor body and being formed by a first channel defined in the first substrate and an opposing second channel defined in the second substrate, a first inlet for introducing a first fluid flow to the first channel, a second inlet for introducing a second fluid flow to the second channel, a first outlet for permitting the first fluid flow to exit the first channel, a second outlet for permitting the second fluid flow to exit the second channel, a membrane disposed in the pathway between the first and second channels and having a plurality of pores sized to selectively capture, in the first channel, a biological source material and to permit biological products to be collected from the bioreactor.

A cell processing system includes at least one processor connectable to a source container filled with a biological fluid, the processor including a spinning membrane configured to receive and separate target cells from the biological fluid, the target cells exiting at a first outlet, first and second containers selectively connected to the first outlet; and a magnet. The system also includes a controller configured to operate the spinning membrane to receive biological fluid and to direct the target cells to the first container, to pause to permit magnetic particles to be associated with the target cells in the first container, to operate the spinning membrane to receive the contents of the first container with the magnet applied to the target cells associated with the magnetic particles, to remove or deactivate the magnet, and to transfer the target cells to the second container.

The present invention provides for a method and transport system for conditioning micro algae grown in a commercial farm and transporting to a final destination while maintaining conditions that allow the microalgae to remain alive and healthy during transit.

Microfluidic devices, systems, and methods providing for an invasion assay using microfluidic culture systems.

A system for performing a gas-liquid mass transfer includes a container bounding a compartment and having a top wall, a bottom wall, and an encircling sidewall extending therebetween. A tube has a first end and an opposing second end, the first end of the tube being disposed within the compartment of the container. A nozzle is disposed within the compartment of the container and has at least one outlet, the nozzle being coupled with the tube so that a gas can be passed through the tube and out the at least one outlet of the nozzle. The nozzle is sufficiently buoyant so that when a fluid is disposed within the compartment of the container, the nozzle floats on the fluid.

A cell processing system includes at least one processor connectable to a source container filled with a biological fluid, the processor including a spinning membrane configured to receive and separate target cells from the biological fluid, the target cells exiting at a first outlet, first and second containers selectively connected to the first outlet; and a magnet. The system also includes a controller configured to operate the spinning membrane to receive biological fluid and to direct the target cells to the first container, to pause to permit magnetic particles to be associated with the target cells in the first container, to operate the spinning membrane to receive the contents of the first container with the magnet applied to the target cells associated with the magnetic particles, to remove or deactivate the magnet, and to transfer the target cells to the second container.

Cells may be grown in a bioreactor, and the cells may be activated by an activator (e.g., a soluble activator complex). Nutrient and gas exchange capabilities of a closed, automated cell expansion system may allow cells to be seeded at reduced cell seeding densities, for example. Parameters of the cell growth environment may be manipulated to load the cells into a particular position in the bioreactor for the efficient exchange of nutrients and gases. System parameters may be adjusted to shear any cell colonies that may form during the expansion phase. Metabolic concentrations may be controlled to improve cell growth and viability. Cell residence in the bioreactor may be controlled. In embodiments, the cells may include T cells. The cells may include T cell subpopulations, including regulatory T cells (Tregs), for example.

A microperifusion system includes at least one perifusate reservoir module having N receptacles and at least one port to communicate a pressurizing gas into or out from the respective perifusate reservoir module. A corresponding perifusion chamber module having M microperifusion channels is mechanically coupleable to at least one perifusate reservoir module to thereby form, when coupled, a sealed fluid communication between a selected first number of the N receptacles and a selected second number of the microperifusion channels. A control system module is coupleable to each perifusate reservoir and each perifusion chamber to control a flow of pressuring gas communicated into or out from the perifusate reservoir sense an effect of a microperifusion test operation occurring in each microperifusion channel.

Methods, devices, and systems for isolating nucleic acid e.g., in a point of need setting, featuring a housing with a binding chamber therein, the binding chamber comprising a binding component capable of binding nucleic acid or other molecule or biomolecule of interest, and at least one fluid chamber for housing a sample or other solutions such as but not limited to buffers fluidly connected to the binding chamber. The fluids in the fluid chamber can be conveyed to and from the binding chamber, for example with the use of an actuator.

According to one embodiment, a culture vessel includes a rigid bottom part and a wall part. The wall part has a culture medium inlet and includes a deformable portion. The culture vessel allows the deformable portion to deform so as to change the capacity of the culture vessel when a pressure of the internal space of the culture vessel varies.
