Abstract
The present disclosure provides devices, systems, methods and kits for processing a sample. In some cases, a sample is processed in preparation for an assay (e.g., polymerase chain reaction and immunofluorescence-based target detection) by an analytic device. In some cases, the processing is automated. In some cases, the processing is substantially automated. The systems provided herein can comprise a cartridge (e.g., one-time use) and a dock (e.g., re-useable) for receiving the cartridge. In some cases, the devices and systems provided herein are portable.

-75. (canceled)
A sample processing cartridge, comprising:
- a sample chamber comprising a filter configured to capture one or more nucleic acid molecules from a sample in said sample chamber;
- a well fluidly coupled to said sample chamber by a first conduit, said well configured to contain a reagent;
- one or more assay tubes, wherein a given assay tube of said one or more assay tube is fluidly coupled to said sample chamber via a second conduit;
- and
- a first opening fluidly connected with said first conduit, wherein said first opening is configured to fluidly connect a fluid flow unit to said first conduit, wherein said fluid flow unit is coupled to a controller configured to receive instructions from a mobile electronic device for processing of said sample, and in accordance with said instructions, (i) direct said fluid flow unit to subject said reagent to flow from said well along said first conduit to said sample chamber, to provide a solution comprising said reagent and said one or more nucleic acid molecules in said sample chamber, and (ii) direct said fluid flow unit to subject said solution to flow from said sample chamber along said second conduit to said one or more assay tubes, such that said given assay tube receives at least a portion of said solution.
A method for processing a sample, comprising (a) activating a system comprising at least two multi-directional pumps in fluid communication with a fluid flow path for processing said sample, which fluid flow path does not include any valves, (b) subjecting fluid in said fluid flow path to flow along a first direction upon application of a first pressure drop by a first multi-directional pump of said at least two multi-directional pumps and a second pressure drop by a second multi-directional pump of said at least two multi-directional pumps, and (c) subjecting fluid in said fluid flow path to flow along a second direction different than said first direction upon application of a third pressure drop by said first multi-directional pump and a fourth pressure drop by said second multi-directional pump,
- wherein said first pressure drop is different than said second pressure drop,
- wherein said third pressure drop is different than said fourth pressure drop, and
- wherein (i) said first pressure drop is different than said third pressure drop, or (ii) said second pressure drop is different than said fourth pressure drop.
