A method for preparing a sample by utilizing a shearing force in the presence of a size stabilizer to break apart the sample to obtain nucleic acid molecules in a usable size range. Once nucleic acid molecules are obtained, magnetic nanoparticles are used to concentrate and clean the nucleic acid molecules for further testing.

Method and system for sample preparation

A filtration column assembly is provided for use in combination with a disposable cartridge of a diagnostic assay system. The filtration column assembly includes a column matrix material configured to filter a fluid sample, a tubular column configured to sealably engage a filtration chamber of the disposable cartridge and a cap configured to be inserted into an end of the tubular column and define a passageway to direct the sample fluid from the second end of the tubular column into a collection cavity disposed adjacent the filtration chamber. The tubular column defines (i) a column cavity for receiving the column matrix material, (ii) a first end having an opening for receiving the fluid sample and configured to retain the column matrix material, and (iii) a second end, receiving the fluid directing cap, and having an opening to dispense a filtered fluid sample from the column cavity.

Filtration column assembly for diagnostic assay system

A disposable cartridge for preparing a nucleic acid sample including a stationary cartridge body and a cylindrical rotor rotationally mounted to the cartridge body. The cartridge body includes: (i) a cylindrical surface defining a fixed port and (ii) a syringe barrel defining a bore in fluid communication with the fixed port. When the disposable cartridge is disposed in combination with an assay system, syringe barrel is configured to receive a moveable plunger, i.e., to stroke the plunger into and out of the barrel. The rotor is seated within a cavity of the cartridge body such that a mating surface thereof slideably engages a cylindrical surface of the cavity. The rotor comprises a plurality of chambers fluidly connecting to a plurality of ports along the mating surface at different radial positions such that at least one of the chambers is fluidly connected to one of the ports by a connecting channel. Rotation of the rotor aligns one of the rotor ports with the fixed port such that fluid may be moved into and out of the chambers in response to axial displacement of the moveable plunger.

A fluid delivery system having a rotating reservoir insert and a cartridge body. The rotating reservoir insert having a plurality of reservoirs in communication with ports on the external surface of the insert. The ports are positioned such that upon rotation the port is in-line with a fluid extracting device, such as a syringe, capable of extracting fluid from the reservoir.

Multi-chamber rotating valve

A method for preparing a sample by utilizing a shearing force in the presence of a size stabilizer to break apart the sample to obtain nucleic acid molecules in a usable size range. Once nucleic acid molecules are obtained, magnetic entanglement particles are used to concentrate and clean the nucleic acid molecules for further testing.
