Grating coupling

The affinity (interaction strength), multiple interactions, and the changes in concentration can be also monitored from those studies. To deliver data in real time, the natural phenomenon of surface plasmon resonance (SPR) is employed. Since the refractive index (r ) at the interface changes as molecules are immobilized on the sensor surface, instant measure of r provides real-time assessment. The Tlcxchip platform exploits grating-coupled SPR (GC-SPR) for this purpose. [Pg.235]

Several techniques can be employed to couple an optical beam propagating in free space into a thin-film optical waveguide. Grating coupling and prism coupling (Fig. 15.4) are briefly outlined here, since these methods are applied in actual reverse waveguide and MCLW configurations, respectively. [Pg.403]

The grating-coupled nanoporous-silica-supported reverse waveguide chip was also applied for monitoring the attachment and spreading of Human Dermal Fibroblast cells to the surface16. As in the bacteria experiments, the waveguide surface was coated with a thin layer of poly-L-lysine layer to improve cell attachment and spreading. [Pg.410]
