Biosensor platforms solutions for quantitation: direct detection assays sector - Medical / Health Care
In direct detection assays, AuNPs are chemically bound to the unclad optical fiber surface. Receptor ligands are subsequently functionalized to the AuNPs. During detection, target analytes bind directly to the receptor ligands. Formation of analyte-receptor complexes induces a local change of refractive index near the sensing surface, producing an optical response proportional to the mass concentration of the bound target analytes.
