Systems and methods for detection and quantification of analytes
First Claim
1. A sample analysis reader for detecting the presence, absence, and/or a quantity of a target analyte, comprising:
- a dock for physically coupling the sample analysis reader to a cartridge, the cartridge comprising a housing with analyte detection reagents and an electrochemical sensor stored therein;
a magnetic field generator configured to localize a magnetic particle if present when the cartridge is coupled to the sample analysis reader;
a circuit having a cartridge detection unit comprising electrical pins for electrically coupling the sample analysis reader to the cartridge;
a processor; and
a non-transitory computer-readable medium having instructions stored thereon, wherein the instructions, when executed by the processor, cause the processor to process electrical signals received from the electrochemical sensor of the cartridge via the circuit.

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. In some embodiments, the reader component communicates 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.
