A recently granted patent (Publication Number: US11921107B2) discloses an innovative assay device designed for efficient detection of analytes in liquid samples. The device comprises a liquid sample addition zone, a reagent zone, a detection zone with capture elements, and a wicking zone to facilitate fluid flow. Notably, the device includes a reagent addition zone strategically positioned along the fluid flow path to control the sample size and interrupt the flow of the sample when necessary. This feature ensures precise and controlled movement of the liquid sample through the device, enhancing the accuracy of the assay results.

Furthermore, the patent claims detail a method for performing assays using the device, involving the addition of a liquid sample and reagent to specific zones, followed by capillary-driven movement of the sample through the device. The method includes steps such as detecting the analyte of interest in the detection zone and flowing the sample into the wicking zone. Additionally, the method incorporates the use of labeled reagent materials and capture elements for efficient detection and generation of signals. Overall, the patented device and method offer a comprehensive solution for conducting assays on liquid samples, ensuring reliable and accurate results through precise control of sample movement and detection processes.
