摘要: A series of multi-dimensional acoustic standing waves is set up inside a growth volume of a bioreactor. The acoustic standing waves are used to hold a cell culture in place as a nutrient fluid stream flows through the cell culture. Biomolecules produced by the cell culture are collected by the nutrient fluid stream and separated downstream of the cell culture.

摘要: A workstation for processing particles entrained in a fluid includes a consumable portion and a reusable portion. The consumable portion is mounted to the reusable portion to form a fluid chamber in which an acoustic wave can be generated. The consumable portion implements a closed, isolated fluid environment that is managed using components of the reusable portion, such as valves, sensors and pumps. The workstation can be operated to retain particles from the fluid via the acoustic wave and provide a new fluid media to the retained particles. Following processing, the consumable portion can be removed and discarded.

摘要: Beads with functionalized material applied to them are exposed to an acoustic field to trap or pass the beads. The beads may include or be free of ferro magnetic material. The beads may be biocompatible or biodegradable for a host. The size of the beads may vary over a range, and/or be heterogenous or homogenous. The composition of the beads may include high, neutral or low acoustic contrast material. The chemistry of the functionalized material may be compatible with existing processes.

摘要: An acoustophoretic system is controlled and driven to attain a desired level of performance. An RF controller and a driver provide a frequency and power to an acoustic transducer, which can be implemented as a piezoelectric element, which presents a reactive load or a complex load. A controller implements a control technique for efficient transducer operation. The control technique can locate a frequency for operation that is at a reactance minimum or maximum for the system to produce a modal pattern and to provide efficient operation of the transducer. A method of detecting a minimum or maximum reactance in a acoustophoretic system used to trap, separate, deflect, cluster, fractionate or otherwise process particles or secondary fluids or tertiary fluids in a primary fluid and utilizing the frequency of the detected reactance to operate the acoustophoretic system.

摘要: Methods and systems for separating material from a host fluid use an acoustophoresis device. These methods and systems can deflect material (e.g., a second fluid, cells, beads or other particles, exosomes, viruses, oil droplets) in host fluid streams at high flow rates.

摘要: Methods are disclosed for separating beads and cells from a host fluid. The method includes flowing a mixture containing the host fluid, the beads, and the cells through an acoustophoretic device having an ultrasonic transducer including a piezoelectric material driven by a drive signal to create a multi-dimensional acoustic standing wave. A drive signal is sent to drive the at least one ultrasonic transducer to create the multi-dimensional acoustic standing wave. A recirculating fluid stream having a tangential flow path is located substantially tangential to the standing wave and separated therefrom by an interface region. A portion of the cells pass through the standing wave, and the beads are held back from the standing wave in the recirculating fluid stream at the interface region. Also disclosed is an acoustophoretic device having a coolant inlet adapted to permit the ingress of a cooling fluid into the device for cooling the transducer.

摘要: Acoustophoretic devices and methods for concentrating targeted biological cells in a reduced volume using multi-dimensional acoustic standing waves are disclosed. The methods include flowing a mixture of a host fluid and the biological cells through an acoustophoretic device. The acoustophoretic devices include an inlet, an outlet, and a flow chamber having an ultrasonic transducer-reflector pair. Biological cells, such as T cells, are separated from a host fluid for utilization in allergenic or autologous cell therapies. The disclosed devices and methods are capable of concentrating biological cells to at least 100 times their original cell concentration. The disclosed methods and devices are further capable of decreasing an original feed volume to a final concentrated volume that is less than one percent of the original feed volume.

摘要: Methods for generating particulate clusters and nodal trapping lines having desired widths are disclosed. The devices include an acoustic chamber having an inlet and an outlet. An ultrasonic transducer and reflector create a multi-dimensional acoustic standing wave that generates particulate clusters separated by a channel of fluid running therebetween and creates nodal trapping lines. The frequency of the multi-dimensional acoustic standing wave can be selectively tuned so as to selectively control at least one of (a) a width of each particulate cluster, or (b) a width of each channel of fluid. The frequency of the multi-dimensional acoustic standing wave can also be selectively tuned so as to selectively control the width of each nodal trapping line. Also disclosed are particulate clusters separated by a channel of fluid, wherein a ratio of the widths of the particulate clusters and the channel of fluid can be varied as desired.
