Show more >Surface plasmon resonance (SPR)-based biosensors are an integral and indispensable aspect of present-day pathology, owing to its efficient real-time and label-free detection capabilities. Enhancing the sensitivity of these sensors is of paramount importance as it indirectly affects the detection limits of biomolecules. In this simulation work, we make use of antireflective coatings (ARCs) (double and multi-layered), made up of nanomaterials with alternating high and low refractive indices (R.I.) (TiO2/SiO2, TiO2/MgF2, Nb2O5/SiO2 and Nb2O5/MgF2); to enhance the sensitivity of Si-Transition Metal Dichalcogenides (TMDCs)-based SPR sensors. To summarize the entire outcome, our simulation predicts the sensitivity of the TiO2-SiO2-Au-Si-TMDC configuration to be 284 degRIU-1 at 633 nm of incident light wavelength.Show less >
