Abstract textThe present invention relates to affinity biosensing using polarization of light scattering of aggregated noble metallic nanostructures to determine concentration of an analyte in a test sample. This new sensing system utilizes the changes in polarized plasmonic scattering from nanostructures as the nanostructures aggregate due to binding of the analyte to a binding partner attached to the surface of the metallic nanostructure. |
