Sensitive Surface Plasmon Resonance biosensor based on a photonic crystal and bimetallic configuration
In this paper, we present and numerically demonstrate a highly sensitive photonic crystal (PC) Surface Plasmon Resonance (SPR) sensor. This proposed sensor consists of an Ag-Au bimetallic configuration that integrates the better evanescent field enhancement of silver, the higher resolution in the reflectivity minimum of silver, and the high chemical of gold. In comparison to most convenient SPR sensors which use single gold films, this PC-bimetallic configuration is shown theoretically to possess a narrower resonance width, smaller minimum reflectance and higher sensitivity, which makes it a much better choice to be employed for SPR biosensing applications.
