Nanostructure-Enhanced Surface Acoustic Waves Biosensor and Its Computational Modeling
Insertion loss spectra for a SAW sensor with 9 nanopillars having a height of 100 nm (a), 150 nm (b), and 250 nm (c) before and after the adsorption of a 100 nm thick PMMA film with each insert showing a zoom-in view of the peak frequency. (d) Variation of the differential IL with the height of nanopillars.
