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.

An embodiment provides a method for treating a body fluid of a patient, including: removing the body fluid from a patient; applying a treatment to the body fluid, wherein the treatment comprises an antibody that joins with an aging process targeted antigen (TA) in the body fluid to form an antibody-TA complex, wherein the antibody comprises a tag sensitive to an illumination; removing the antibody-antigen complex from the body fluid; and returning the body fluid to the patient. Other aspects are described and claimed.

A method of operating a magnetic selector is provided. The magnetic selector includes a housing including a floor having a floor surface, a magnet carrier disposed on an opposite side of the floor from the floor surface and having at least one magnet disposed thereon, the magnet carrier being moveable relative to the floor between a first state wherein the magnet carrier is adjacent the floor and a second state wherein the magnet carrier is spaced from the floor. The method includes disposing a container on the floor surface, moving the magnet carrier to the first state to apply a magnetic field to a fluid in the container, moving the magnet carrier to the second state from the first state to disengage the magnetic field from the container, and removing the container.

A magnetic selector includes a housing configured to receive a container and having a floor upon which the container is disposed. The selector also includes a magnet carrier disposed on an opposite side of the floor from the container. The magnet carrier has at least one magnet disposed thereon and being moveable relative to the floor between a first state wherein the magnet carrier is adjacent the floor and a second state wherein the magnet carrier is spaced from the floor. The selector may include a door. The magnetic selector is usable in a fluid processing system that includes a fluid processor connectable to a source container filled with a biological fluid. A container is disposed in the magnetic selector and connected to the processor along a fluid pathway. The processor is configured to separate the biological fluid from the source container into at least two streams of material.

An embodiment provides a method for treating a body fluid of a patient with an inflammatory cytokine storm, including: removing the body fluid from a patient; applying a treatment to the body fluid, wherein the treatment comprises an antibody that joins with an antigen in the body fluid to form an antibody -antigen complex; removing the antibody-antigen complex from the body fluid; and returning the body fluid to the patient. Other aspects are described and claimed.

Assemblies, systems, and methods for isolation of target material are provided. In various embodiments, an assembly for target material isolation includes a housing having an upper portion and a lower portion together defining an inner chamber. The inner chamber includes a semi-toroidal shape and the semi-toroidal shape defines a longitudinal axis. The assembly further includes one or more fluidic connection from the exterior of the housing to the inner chamber. An isolation material (e.g., polymer wool and/or magnetic beads) may be disposed within the inner chamber. A system includes a configured to fit at least a portion of the housing and releasably couple the assembly. Upon activation of the motor, the assembly may rotate about the longitudinal axis. An angle of the platform may be adjustable to thereby change the angle of the longitudinal axis about which the assembly rotates.
