Long-period gratings

Long period gratings modified by the deposition of a self-assembled colloid monolayer of gold have been shown to enhance SRI sensitivity, which was attributed to the localized surface plasmon resonance (LSPR) of gold nanoparticles61. The system was used after functionalization of the gold nanoparticles with dini-trophenyl (DNP) antigen, for the detection of anti-(DNP) with a limit of detection as low as 9.5 x 10 10 M. [Pg.71]

Also the use of tapered long period gratings (TLPGs) is a step toward the use of structures with reduced cladding radius, which provide an additional sensitivity gain with respect to UV-written LPGs and are more robust than etched UV-LPGs66. [Pg.71]
