Method and apparatus for controlling acoustic treatment of a sample including a liquid. A processing volume in which the sample is acoustically treated may be controlled, e.g., by positioning a suitable element so as to reduce and/or eliminate a headspace size at a sample/gas interface. An interaction between the acoustic energy and the sample may be controlled, e.g., by using a headspace control element positioned at least partially in the sample that helps to reduce splashing or other sample ejection that would otherwise occur.

Methods and systems for acoustically treating material using a continuous process in which material may be caused to flow in a continuous or intermittent fashion into/out of an acoustic treatment chamber where the material is exposed to focused acoustic energy. The methods and systems may be arranged to permit continuous processing for extended periods while an acoustic energy source operates at a relatively high power output. Treatment chambers may include features such as an acoustic window and/or a chamber wall which may comprise an acoustically reflective material or a gas/wall interface that serves to reflect acoustic energy to form one or more secondary focal zones. Treatment system configurations relating to arrangements of a treatment chamber relative to an acoustic source and coupling medium, material flow paths, and others are provided.

Methods and systems for acoustically treating material using an acoustic energy system having a movable outer surface that contacts a sample holder. The outer surface may be cylindrical and rotate about a central axis, e.g., so that a sample holder may be driven to move by the outer surface. Acoustic energy may be emitted from within the outer surface to a treatment area outside of, and near, the outer surface. Thus, a sample holder in contact with the outer surface may have a sample exposed to acoustic energy while rotation of the outer surface may move the sample holder relative to treatment area. One or more additional rollers or other components may bias the sample holder into contact with the outer surface, to e.g., so the sample holder is squeezed between the outer surface and a roller or other biasing component.


The present disclosure relates to a composition that includes an apolipoprotein and a lipid bilayer, and methods and systems for preparing the composition. The apolipoprotein may be incorporated within at least a portion of the lipid bilayer. The lipid bilayer may form a liposome or other suitable carrier for transporting the apolipoprotein. The apolipoprotein incorporated lipid bilayer may provide a suitable delivery vehicle for the apolipoprotein to the body. Compositions of the present disclosure may be formed by exposing a mixture of an apolipoprotein and a lipid formulation to focused acoustic energy which, in some embodiments, may result in a liposome that at least partially encapsulates the apolipoprotein. In some embodiments, apolipoprotein A-V may be incorporated within a liposome, where the apolipoprotein A-V is suitably bioactive, or therapeutic, when delivered to cells and/or into the body of a patient.

A treatment vessel may allow a user, or automated system, to manipulate sample material within a treatment area during processing (e.g., focused acoustic treatment), as well as subject the sample material to a staged processing protocol. The vessel may include openings for receiving/discharging the sample material. Walls within the vessel may be movable between various positions, to permit or obstruct flow of sample material into or out from a treatment area. The wall(s) may push the sample material within the vessel, as well as adjust pressure levels within the treatment area. In some embodiments, an acoustic treatment system may include a flexible coupling medium that may be deformed toward the vessel upon an application of suitable pressure thereto. When the medium presses up against the vessel, defects (e.g., particles, bubbles, interfaces, etc.) that may otherwise be present along the acoustic wave path may be reduced.
