AI Technical Summary

Technical Problem

Existing technologies are insufficient in terms of sensitivity, accuracy, and total measurement time (TAT) for detecting small-volume liquid samples, especially in point-of-care testing devices and methods, making it difficult to accurately analyze specific analytes in liquid samples, particularly for rapid detection of the COVID-19 virus.

Method used

Samples and reagents are mixed by oscillating the entire optical measurement system, including the electromagnetic radiation source, detection unit, and container, ensuring that the container remains in a constant position relative to the light source and detection unit during measurement. Sample processing is performed using the Egoo device and SIBA amplification technology.

Benefits of technology

It significantly improves the sensitivity and accuracy of detection, enabling rapid and accurate COVID-19 virus testing, reducing false positive results, and is suitable for on-demand home testing applications.

Abstract

The invention relates to a method and a device for quantitatively detecting the presence or absence of an analyte in a liquid sample, said method and device comprising: an analyte detection assembly comprising an electromagnetic radiation source, a unit for detecting electromagnetic radiation and a container containing a detection liquid, said container being positioned between said source and said detection unit such that electromagnetic radiation is radiated from said source to said detection unit through said detection liquid, wherein the mixing of the contents of said detection liquid is performed by oscillating said detection assembly with a circular or elliptical motion using a unit suitable for this, whereby the positioning of said container relative to said source and said unit is constant throughout the completion of the measurement of the amount of analyte in the liquid sample.
