Optical Surface plasmon resonance (SPR) biosensors represent the most advanced and developed optical label‐free biosensor technology. Optical SPR biosensors are a powerful detection and analysis tool that has vast applications in environmental protection, biotechnology, medical diagnostics, drug screening, food safety and security.

Surface plasmon resonance (SPR) is proven technique to develop the label‐free biosensor for quantification and characterisation of bio‐molecular interactions from the healthcare industry to fundamental research in proteomics and genomics [1, 2].

The most widely used biosensors are optical-based devices such as surface plasmon resonance (SPR)-based biosensors and fluorescence-based biosensors. The Surface Plasmon Resonance (SPR) biosensor is a type of biosensor which is very powerful for detecting and determining the specificity, affinity, and kinetic parameters of macromolecular bonds. The working principle of this biosensor uses metals such as gold (Au), silver (Ag), and aluminum (Al) to excite surface plasmon waves which are very sensitive to changes in the refractive index on Mathcad programs demonstrated that only TM waves could be used for surface plasmon resonance on a metal surface in Otto configuration or Kretschman configuration. With Rouard's recursive method to numerically simulate light reflectivity in a multilayered system, we found benchmarks of SPR biosensors, and got linear relationships about the shift of the SPR angle to the surface concentration of biological films. Summary. Surface plasmon resonance (SPR) biosensors belong to label-free optical biosensing technologies. The SPR method is based on optical measurement of refractive index changes associated with the binding of analyte molecules in a sample to biorecognize molecules immobilized on the SPR sensor.

It is observed that highest sensitivity A Surface Plasmon Resonance (SPR) biosensor for identifying and quantifying bio-molecules and their interactions that operate s deep into the infrared (3 -11 µm wavelengths), has potential for recognition based both on selective binding and characteristic vibrational modes. If mass is bound to the surface within this 300 nm range then it perturbs the plasmon and, for a photon of fixed wavelength, shifts the resonance angle. If the plane of the metal surface is fixed, then the resonance wavelength can be identified by scanning through a range of angles of incidence for the photon and determining the resonance angle (Mullet et al., 1998).
