Gold Nanoshells for Lateral Flow Assays
Antibodies and other amine-containing biomolecules efficiently bind to Gold Nanoshells using EDC-NHS chemistry to make highly stable conjugates. Gold Nanoshells have been integrated into dozens of lateral flow assay systems, offering a clear advantage in stability, reproducibility, dynamic range, and sensitivity. Gold Nanoshells provide an ultrabright label for lateral flow – up to 20× increases in lateral flow diagnostic sensitivity over 40 nm gold.
