A recently granted patent (Publication Number: US11913949B2) discloses a multiparameter lateral flow membrane designed for testing multiple ligands or analytes in a liquid sample. The membrane features a microporous layer with two or more flow lanes running parallel and adjacent to each other, separated by hydrophobic channels. Each flow lane includes a detection zone with a binding agent, and the lanes are isomorphic, zig-zag, or meander-shaped. The detection zones in adjacent flow lanes are positioned along a common line in the direction of fluid flow, enhancing the efficiency of the testing process.

Furthermore, the patent details the dimensions, materials, and components of the multiparameter lateral flow membrane, including the width of hydrophobic separation channels, the use of nitrocellulose for the membrane layer, and the selection of binding agents such as antibodies or aptamers. The patent also covers the inclusion of control zones, conjugate zones, and the manufacturing process involving laser-etching and application of detection zones. Additionally, the patent extends to a multiparameter lateral flow immunoassay device and methods for conducting immunological tests using the membrane. Overall, the patented technology offers a sophisticated and efficient solution for conducting multiparameter lateral flow tests with precision and accuracy.
