<p><b>Dual-polarization interferometry</b> (<b>DPI</b>) is an analytical technique that probes molecular layers adsorbed to the surface of a <a href="page.php?w=Waveguide_%28optics%29">waveguide</a> using the <a href="page.php?w=evanescent_wave">evanescent wave</a> of a <a href="page.php?w=laser">laser</a> beam. It is used to measure the <a href="page.php?w=conformational_change">conformational change</a> in proteins, or other biomolecules, as they function (referred to as the <a href="page.php?w=conformation_activity_relationship">conformation activity relationship</a>).</p><p>
