Comparative Study of Four Coloured Nanoparticle Labels in Lateral Flow Immunoassay
Nanomaterials, 2021 The detection limit of lateral flow immunoassay (LFIA) is largely determined by the properties of the label used. We compared four nanoparticle labels differing in their chemical composition and colour: (1) gold nanoparticles (Au NPs), red; (2) Au-core ...
