摘要： Beads with functionalized material applied to them are exposed to an acoustic field to trap, retain 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. The acoustic field may be generated, for example, in an acoustic angled wave device or in an acoustic fluidized bed.

摘要： Separation of materials is achieved using affinity binding and acoustophoretic techniques. A column provided with a fluid mixture of materials for separation and support structures may be used with acoustic waves to block flow of the support structures. The support structures can have an affinity for one or more materials in the fluid mixture. By blocking flow of the support structures, materials bound or adhered to the support structure are also blocked.

摘要： Methods and systems for processing material in 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： Acoustic perfusion devices for separating biological cells from other material in a fluid mixture are disclosed. The devices include an inlet port, an outlet port, and a collection port that are connected to an acoustic chamber. An ultrasonic transducer creates an acoustic standing wave in the acoustic chamber that permits a continuous flow of fluid to be recovered through the collection port while keeping the biological cells within the acoustic chamber to be returned to the bioreactor from which the fluid mixture is being drawn.

摘要： Separation of particles or droplets from a host fluid may be achieved using a transducer and/or reflector that is a thin, non-planar structure. The thin non-planar structure improves operation of an acoustic standing wave generated by an acoustic transducer. The structure may operate as a pressure release boundary and may be constructed as plastic film.

摘要： A method for separating a second fluid or a particulate from a host fluid is disclosed. The method includes flowing the mixture through an acoustophoretic device comprising an acoustic chamber, an ultrasonic transducer, and a reflector. The transducer includes a piezoelectric material driven by a voltage signal to create a multi-dimensional acoustic standing wave in the acoustic chamber. A voltage signal is sent to drive the ultrasonic transducer in a displacement profile that is a superposition of a combination of different mode shapes that are the same order of magnitude to create the multi-dimensional acoustic standing wave in the acoustic chamber such that the second fluid or particulate is continuously trapped in the standing wave, and then agglomerates, aggregates, clumps, or coalesces together, and subsequently rises or settles out of the host fluid due to buoyancy or gravity forces, and exits the acoustic chamber.
