NALF is an abbreviation for "Nucleic Acid Lateral-Flow", which describes technologies detecting molecular amplification products on a lateral-flow strip. Typically NALF systems combine lateral-flow strips with a microfluidic system.

The method used by AMODIA has the following specifications:

• the amplification product is labeled during amplification
• to this labeled amplification product a labeled probe is hybridized (sequence verification !)
• one label binds to the particles on the lateral-flow strip
• the other label binds to capture molecules immobilized on the membrane of the LFD
• all target molecules are amplified in parallel with an internal control, which binds according to the same principle on a separate line
• the proper functioning is displayed by an additional line (assay control)

AMODIA offers several variations of lateral-flow strips (e.g. the MultiFlow^® Basic), which differ in the number of amplification products detectable in parallel.

Within a research project (PTJ: 0315656A) AMODIA was able to demonstrate the combination of lateral-flow strip and microfluidics on a chip.
