Interactions between biomolecules are detected and analyzed in real time using SPR (Surface Plasmon Resonance) technology. In this technology, a biomolecule is immobilized on a modified gold surface. The other molecule, which may bind to the immobilized molecule, is passed over the gold surface. Once the two molecules interact, the optical properties of the gold surface change. The change in optical property measured is correlated to biomolecular interaction.
