Abstract: (765 Views)
In this paper, we investigate the sensitivity of optical nanobiosensors with respect to the changes of the
background’s optical properties. For this purpose, a nanobiosensor designed and modeled and the effects of changing the grating periodicity and nanoparticle size on enhancing its sensitivity have been investigated. The results show that the sensitivity of optical nanobiosensors to the changes in the background’s optical properties is of the order of 0.01nm / RIU. Also, the change in the size of nanoparticle as well as the change in the grating periodicity shows a red frequency shift.
