The role of the nitrocellulose membranes in a lateral flow immunoassay (LFIA) is highly critical. The membrane acts as the main motor of the test, drawing the samples and conjugates from one end of the strip to the other end. Concurrently, the sample-conjugate complex can be captured by reagents that are pre-bound to the test and control lines.
