Piezoelectric Quartz Crystal Resonators Applied for Immunosensing and Affinity Interaction Studies
Piezoelectric quartz crystals serve as resonator-based transducers for direct and real-time monitoring of immunoaffinity interactions. The measuring system is briefly characterized; several examples for immobilization of antibodies are recommended. The piezoelectric immunoassays employing direct, competitive, and displacement-based formats are demonstrated on examples. The method for kinetic characterization of immunoaffinity interactions is presented.
