A Nanoscale, Tunable and Highly Sensitive Biosensor Utilizing Hyperbolic Metamaterials in the near-infrared Range
Listed in DataCite
A plethora of research in recent years has been reported on biosensing in the surface plasmon resonant systems.
Description
However, very little research has reported the tunable and highly sensitive biosensor in a nanoscale platform. In this Regard, we propose a nanoscale hyperbolic metamaterial (HMM)-based prism coupled waveguide sensor (PCWS) in the near-infrared range.
HMM-layer makes one of the constituents of the PCWS – comprised of periodically arranged assembly of silver nano strips. The structure is numerically simulated by the finite difference time domain method. It is demonstrated that the sensitivity of the reflected light can be tuned through refractive index (RI) of solution.

Moreover, the effects of alteration of constituents of PCWS on the sensitivity have been analyzed. Results show that the sensitivity of PCWS can be harnessed by altering the thickness, slant angle of HMM layer, volume fraction () of metal in HMM-Layerand the incidence angle of light. For this purpose, the structure is numerically simulated by the finite difference time domain method.
In the optimum design of the proposed sensor, the maximum value of sensitivity is achieved as high as S = 3450 nm/refractive index unit with θ=10° and φ=10° and a metamaterial thickness of 250 nm. Moreover, the structure has a nano-scale footprint of 600 nm
