All binding events induce a change in refractive index, and antibody–antigen interactions are no exception. We describe the use of backscattering interferometry to quantify antibody binding without labels and with high sensitivity. As a broad range of antibodies are available, this method represents a general way to selectively detect a wide variety of trace molecules in simple or complex mixtures.
