Abstract:In the recent context of the post-pandemic world, label-free detection has become a crucial technique in various human physiological testing analyses. In this paper, a plasmonic nanosensor is proposed based on a tapered waveguide cavity resonator, which provides label-free detection with high sensitivity for bio-sensing applications. The transmittance curve is studied using the finite difference time domain method. The transmittance curve exhibits dual Fano resonances with the highest sensitivity of 2544.3 nm/… Show more
