A disposable cartridge for mitigating cross-contamination of fluid sample reagents. The disposable cartridge includes a cartridge body defining a syringe barrel having an barrel port operative to inject and withdraw assay fluids in response to the displacement of a syringe plunger. Furthermore, the disposable cartridge includes a rotor defining a plurality of assay chambers in fluid communication with the barrel port through one of a plurality of rotor ports disposed about the periphery of the rotor. Finally, the disposable cartridge includes a flow control system between the barrel and rotor ports which prevents cross-contamination of fluid sample reagents from one assay chamber to another assay chamber.

Flow control system for diagnostic assay system

A disposable cartridge comprises a cartridge body defining at least one syringe barrel having an barrel port configured to inject and aspirate assay fluids by displacement of a barrel plunger and at least one reaction chamber configured to receive and perform diagnostic testing on the assay fluids. The disposable cartridge also includes at least two rotors mounted for rotation to the cartridge body, each of the rotors defining a plurality of ports in fluid communication with at least one of the assay chambers of a respective one of the rotors. The rotors are selectively rotated such that a port of one rotor aligns with a port of the other rotor. At least one of the rotors is disposed in fluid communication with the syringe port of the syringe barrel such that assay fluids may flows from at least one of the assay chambers through the ports of the rotors by displacement of the barrel plunger.

Multiple rotor disposable cartridge for portable diagnostic assay system

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 system and method for preparing a diagnostic fluid sample for use with a fluid assay system. The method comprises the steps of: amplifying the fluid sample to increase the number of cells subject to being tested; drawing a first volume of the fluid sample into a first syringe of a dual-barrel syringe and dispensing the first volume of the fluid sample through a media filter. The method further comprises the steps of placing the bacteria-laced filter into a lysis module; dispensing a first portion of a lysis buffer into the lysis module from the second syringe of the dual-barrel syringe; and dispensing a second portion of the lysis buffer through the media filter into a disposable cartridge of a fluid assay system.

Device system and method for fluid sample collection

A diagnostic assay system for accelerating reagent reactions comprising a base portion receiving a disposable cartridge and a cover portion moveably mounted to the base such that the disposable cartridge may be installed and removed from the base portion. The disposable cartridge includes at least one assay chamber for receiving an assay fluid, and a cartridge body including a syringe barrel operative to move assay fluids into and out of the assay chambers. The diagnostic assay system also includes a heater proximal the at least one fluid assay-containing cavity, operational when the cover portion is in a closed position and configured to heat the assay fluid in one of the assay chambers to accelerate reagent reactions in the disposable cartridge.

System for accelerating reagent reactions in a disposable cartridge

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.

The present invention relates to methods of metallizing nucleic acid molecules and to methods of attaching nucleic acid molecules to conductive surfaces. Methods of detecting target nucleic acid molecules based on these techniques are also disclosed.
