Gold Nanoparticles Coated With Hydrophobin-ProteinA Fusion Protein: Development of a Versatile Immunosensing Platform. [PDF]

Biotechnol Bioeng
The biosensor uses a two‐step method involving Ab‐Vmh2/SpA‐AuNPs. Gold nanoparticles are functionalized with Vmh2/SpA, antibodies and then mixed with analytes. HCl induces aggregation in unbound particles enabling detection through spectral analysis based on analyte interaction and nanoparticle aggregation behavior.
