| Description |
For detecting bio-molecular interaction using long period grating (LPG) we believe that a quantitative data concerning sensitivity for addition of layers on the surface and subsequently to optimize the same appears to be more usefull than defining LPG sensitivity for a surrounding refractive index change in bulk form. For the first time, to the best of our knowledge, we quantify the shift of resonant wavelength (Delta lambda(res)) of the mode of interest around the transition point as a function of unit bi-layer thickness (Delta d) of poly-electrolyte, deposited by ionic self assembly, and subsequently optimize the sensitivity Delta lambda(res)/Delta d. Experimental result show that a shift of similar to 12.5 nm/bi-layer is possible with optimum number of bi-layer deposition.
