Our solutions for lateral flow testing are developed using a laser-based platform-technology that is used to pattern the building blocks (cellulose pad, glass-fibre pad or nitrocellulose membrane) of a lateral flow test. Patterning uniquely shaped fluid-flow paths at specific locations within these blocks allows the creation of flow-controlled lateral flow tests with improved performance (sensitivity and limit-of-detection) and added functionalities (i.e. multiplexing, and quantification). The patterning process is fast, low-cost, non-contact, and suited for both roll-to-roll and batch manufacturing, making it compatible with conventional lateral flow manufacturing.
