Summary: This study investigated Ag-Au bimetallic surface plasmon resonance (SPR) sensors in the Kretschmann configuration. Ag-based sensors have high sensitivity but poor stability, while the addition of an Au capping layer improves chemical resistance and analyte bonding. Numerical modeling and experiments evaluated sensors with different Ag-Au thickness ratios, showing that the best SPR response was achieved with 45 nm Ag and 5 nm Au. The fabricated Ag-Au sensors were characterized, and the results were compared to single-layer Ag and Au sensors. The sensitivity of the thickness-optimized bimetallic layer was 1.5 times higher than that of the single-layer Au sensor.

Summary: This study presents a simple hybrid structure of TiO2-Cu-BaTiO3 that demonstrates high sensitivity and resolution for biosensing applications using an angular interrogation method. Copper (Cu) has been identified as an excellent choice for surface plasmon sensors (SPR) due to its ability to produce finer SPR curves compared to Ag and Au. To overcome copper oxidation, a protective layer of barium titanate (BaTiO3) is incorporated, which not only prevents oxidation but also enhances sensor performance. The addition of a thin adhesive layer of titanium dioxide (TiO2) between the prism base and Cu film further improves sensor performance. Upon optimization, this configuration achieves a sensitivity as high as 552 RIU with a figure of merit (FOM) of 136.97 RIU-1, making it an ideal biosensor design for long-term detection with enhanced accuracy and sensitivity, even using Cu as a plasmonic metal.

Summary: This numerical work proposes two novel designs of long-range surface plasmon resonance sensors (LRSPR) using two different coupling prisms. The performance analysis of the proposed sensor has been investigated using performance parameters such as quality factor (Q), detection accuracy (DA), sensitivity (S), and full-width half maximum (FWHM). The transfer matrix method (TMM) has been used to calculate reflectance. The popular two-dimensional (2D) material, black phosphorus (BP), has been used as the basic recognition element (BRE) due to its optoelectrical features. The maximum values obtained for Q, DA, and S are 3333.25 1/RIU, 250 degree-1, and 13.33333 degree/RIU for the 2S2G coupled sensor design and 3055.5 1/RIU, 83.33 degree-1, and 36.66667 degree/RIU for the BK7 coupled sensor design. The theoretical investigation is carried out using an operating wavelength of 633 nm based on the principle of attenuated total reflection (ATR).

Summary: In this paper, a bimetallic layer-based surface plasmon resonance (SPR) biosensor using Silver, BaTiO3, and transition metal dichalcogenide material (MoS2/MoSe2/WS2/WSe2) is proposed. The biosensor is built on the attenuated total reflection (ATR) method and the Kretschmann configuration is used for evaluating its performance parameters. Numerical analysis demonstrates that the proposed biosensor structure exhibits significantly improved sensitivity compared to the conventional structure. By optimizing the structure with specific layers of metallic silver, MoS2, and BaTiO3, a maximum sensitivity of 446 degrees/RIU is achieved. These findings open up possibilities for a novel heterostructure-based SPR biosensor for gas and biological sensing in the visible region.

Summary: We propose a new biosensor based on surface plasmon resonance (SPR) that can detect two commonly used buffers: Dulbecco Phosphate Buffered Saline (PBS) and TRIS-Borate-EDTA Buffer (TBE). The biosensor combines SrTiO3 (STO) and two-dimensional (2D) materials, and using STO can significantly enhance sensitivity compared to traditional SPR biosensors. Additionally, employing a single sheet of graphene (SSG) further improves sensitivity. The highest sensitivities achieved for PBS and TBE buffers are 327.023 and 320.581 degrees/RIU, respectively, using the structures SSG/35 nm Ag/14 nm STO and SSG/50 nm Ag/12 nm STO. Furthermore, the use of WSe2 as a 2D nanomaterial results in maximum sensitivity due to its lower real part of the refractive index. These findings demonstrate the effectiveness of the proposed SPR biosensor for biomedical applications.

Summary: This article presents a one-dimensional binary photonic crystal (BPC) as a methanol sensor with inverted symmetry. The BPC structure consists of (Si/SiO2)(N) (SiO2/Si)(N), where N is the number of periods. The porous silicon material is assumed to be infiltrated with the measurand, replacing the air in the void space with a chemical compound of higher refractive index, resulting in a redshift of the Bragg peak. By tuning the transmission spectra, the type of chemical compound in the silicon pores can be accurately determined. The current sensor achieved a sensitivity of 1186.1 nm/RIU, making it highly suitable for industrial or commercial detection of liquids and gases.
