Lateral flow immunoassays (LFI) are widely used worldwide for the detection of different analytes because they combine multiple advantages such as low production cost, simplicity, and portability, which allows biomarkers detection without requiring infrastructure or highly trained personnel. This work aims to provide solutions to some steps of the LFI manufacturing process, particularly the controlled dispensing of reagents in the form of test lines. Automating this stage1 of LFI production provides greater control over the amounts of reagents deposited and greater reproducibility between and within batches.
