Optimized prism-based surface plasmon resonance sensor for malaria detection: role of 2D nanomaterials for an enhancement in sensitivity and accuracy.

A prism-based surface plasmon resonance (SPR) sensor is presented for the identification of various phases of malaria. The suggested structure is composed of BK7 prism, copper as metal layer, titanium dioxide (TiO), and tellurium dioxide (TeO) as a dielectric layer, black phosphorous (BP) as 2D material and an analyte layer. The thickness and the layer count of the suggested structure have been optimized for the analysis of angular reflectivity.

Numerical Study of Titanium Dioxide and MXene Nanomaterial-Based Surface Plasmon Resonance Biosensor for Virus SARS-CoV-2 Detection.

A novel surface plasmon resonance-based biosensor for SARS-CoV-2 virus is proposed in this article. The biosensor is a Kretschmann configuration-based structure that consists of CaF prism as base, at which silver (Ag), TiO, and MXene nanolayers are used to enhance the performance. Theoretically, the performance parameters have been investigated by means of Fresnel equations and transfer matrix method (TMM).
