Cartridges, kits, and methods for amplification and detection of analytes
First Claim
1. A sample analysis cartridge comprising:
- an input tunnel that extends from an aperture, the input tunnel configured to permit insertion of a sample collection device having a distal portion adapted to be exposed to a sample comprising a target nucleic acid;
a reagent ball comprising reagents for amplification of the target nucleic acid by an amplification reaction;
a reservoir configured to hold a fluid, the reservoir further configured to receive the sample from the sample collection device and to receive the reagent ball such that the sample is mixed with an effective amount of the reagents for amplification of the target nucleic acid in the fluid of the reservoir to generate amplicons comprising signaling agents;
an analysis channel configured to receive the fluid comprising the amplicons from the reservoir; and
a sensor at least partially disposed in the analysis channel such that the amplicons indicative of at least one of a presence, absence, or quantity of the target nucleic acid in the sample localize over the sensor and the sensor senses signals indicative of at least one of the presence, absence, or quantity of the target nucleic acid in the sample based on reactions between a substrate and the signaling agents of the amplicons localized over the sensor.

Abstract
Devices, systems, and methods for detecting molecules of interest within a collected sample are described herein. In certain embodiments, self-contained sample analysis systems are disclosed, which include a reusable reader component, a disposable cartridge component, and a disposable sample collection component. The reader component may communicate with a remote computing device for the digital transmission of test protocols and test results. In various disclosed embodiments, the systems, components, and methods are configured to identify the presence, absence, and/or quantity of particular nucleic acids, proteins, or other analytes of interest, for example, in order to test for the presence of one or more pathogens or contaminants in a sample.
