Measurement of an analyte with a cartridge

A method of performing an optical measurement of an analyte in a processed biological sample using a cartridge is provided. The cartridge is operable for being spun around a rotational axis. The method comprises: placing the biological sample into a sample inlet; controlling the rotational rate of the cartridge to process a biological sample into the processed biological sample using a fluidic structure; controlling the rotational rate of the cartridge to allow the processed biological sample to flow from the measurement structure inlet to an absorbent structure via a chromatographic membrane, and performing an optical measurement of a detection zone on the chromatographic membrane with an optical instrument. An inlet air baffle reduces evaporation of the processed biological sample from the chromatographic membrane during rotation of the cartridge.

The methods and devices described facilitate the point-of-care implementation of complex diagnostic assays in equipment-free, non-laboratory settings. The invention includes a microfluidic device comprising a reagent-dispensing unit, a sample extraction device and a specimen processing unit.

NANOSPLASH: A SALIVA-BASED DIAGNOSTIC FOR VIRAL INFECTION SUITABLE FOR HOME USE
20220168728 · 2022-06-02 · ·

Provided herein are compositions, methods, assays, and devices for diagnosing and treating a viral infection in a subject and/or detecting a viral nucleic acid in a sample. In one example, a sample is treated in a first chamber and via a closing or twisting operation, the sample is flowed into a second chamber, where any pathogenic nucleic acid is detected by oligonucleotides that are specific to the pathogen under test. Further, the oligonucleotides comprise are cleavage site for a restriction enzyme in the second chamber, which cleaves oligonucleotide-pathogenic nucleic acid hybrid resulting in the exposure of an enzyme that was being held by the oligonucleotide to its substrate, which generates a colorimetric and/or another visual readout (e.g., foam formation). Further, the methods, device, or kits provided herein can be used to detect SARS-CoV-2 in a saliva sample from a human subject as a rapid in home diagnostic test for COVID-19.
