    摘要： Focused acoustic treatment of samples including a target biomolecule, such as cfDNA, may aid in the recovery of the biomolecule from a sample. cfDNA in a sample, whether chemically stabilized or not, may be linked or otherwise bound to histones or other proteins, e.g., by hydrogen bonds of histones or chaperone proteins to DNA and/or covalent crosslinks of such proteins to the DNA. Focused acoustic energy may remove or disrupt such links, aiding in isolation of the cfDNA from the sample.

    摘要： Methods and systems for treating material with focused acoustic energy and/or ultraviolet radiation are described. Sample material may be provided to a single batch vessel or may flow in a continuous or intermittent fashion into/out of a processing chamber within which the material is exposed to focused acoustic energy and/or ultraviolet radiation. Exposure to focused acoustics in a flow through environment may enhance the effects of the radiation on the sample material. Further, in flow-through or single batch arrangements, sample material may be retained exterior to or within a processing chamber by one or more retaining members (e.g., filter, valve, etc.) until a characteristic of the sample material reaches one or more particular criteria (e.g., physical, chemical, biological). Once the criteria of the sample material is attained (e.g., via further treatment), the material is then permitted to flow past the retaining member(s) and through the inlet or outlet of the chamber. Further, focused acoustic processing may be used to treat articles, such as the retaining member(s), rather than only sample material located within an internal processing volume of the chamber.

    摘要： Method and apparatus for transmitting acoustic energy to a sample for treatment by employing a phase change couplant at least adjacent a sample vessel. The phase change couplant may be solid before and after treatment, but liquid during treatment to improve acoustic energy transmission charactersitics.

    摘要： 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.

    摘要： 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, a heat exchanger, inlet/outlet flow arrangements, an inspection window, insert elements that define a treatment volume size or shape, etc. 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.

    摘要： Method and apparatus for holding and/or treating a sample material. A sample may be positioned in a vessel and a crushing force may be applied to the sample material while in the vessel, e.g., by a plunger that is part of a cap to pulverize the sample at cryogenic temperatures. The sample holder may include an acoustic window arranged to admit acoustic energy into the vessel for acoustic treatment of the sample. A flexible film may be used at a portion of the vessel, e.g., at the acoustic window, to cooperate with a plunger for crushing a sample.
