dc.description.abstract | Since infectious diseases, particularly viral infections, have threatened human health and caused huge economical losses globally, a rapid, sensitive, and selective virus detection platform is highly demanded. Enzyme‐linked immunosorbent assay (ELISA) with flat solid substrates has been dominantly used in detecting whole viruses for its straightforwardness and simplicity in assay protocols, but it often suffers from limited sensitivity, poor quantification range, and a time‐consuming assay procedure.
Here, a lipid‐nanopillar‐array‐based immunosorbent assay (LNAIA) is developed with a nanopillar‐supported lipid bilayer substrate with fluorophore‐modified antibodies for rapid, sensitive, and quantitative detection of viruses. 3D- nanopillar array structures and fluid antibodies with fluorophores facilitate faster and efficient target binding and rapid fluorophore localization for quick, reliable analysis on binding events with a conventional fluorescence microscopy setup. LNAIA enables quantification of the H1N1 virus that targets down to 150 virus particles with the 5‐orders‐of‐magnitude dynamic range within 25 min, which cannot be achieved with conventional ELISA platforms. | - |
