Abstract

This paper presents a unified scaling law for biosensor using nanogolds in various structures of nanorods, nanoshells and nanoslits. Analytic formulas are developed by a generalized geometric factor (G) for the resonance wavelength and the associate sensitivity, where G depends on structure types and is defined by: the length and width ratio (for nanorad); the inner and outer diameter ratios of the gold-costed silica shell (for nanoshell); the period (for surface mode) and the ratio of slit height and slit width (for cavity mode). The general feature of the figure of merit and its optimal conditions are derived. The analytic formulas are justified by numerical solutions and show the nonlinear features for a wide range of resonance wavelength.
