A novel approach to multichannel SPR sensing based on encoding information from separate sensing channels into a single optical spectrum is presented. A dual channel SPR sensor using this approach is demonstrated. Attention is given to exploitation of the dual-channel SPR sensor for compensation for background interference and non-specific adsorption of the biomolecules to the surface of the SPR biosensor. Experimental results indicate that background refractive index changes were compensated with accuracy better than 8x1ff5 RIU (refractive index unit); the effect of a temperature change of 3.6 K was reduced by a factor of 13 by the dual-channel sensor. SPR biosensor-based detection of monoclonal anti-dinitrophenyl antibody (a-DNP) with compensation for non-specific adsorption is demonstrated.

“…Sodium (Na) and indium (In) metal are also being used as a metal layer, but sodium is more reactive in nature and indium is very costly [ 100 , 101 ]. Further additional dielectric layers such as TiO 2 , SiO 2 , Ta 2 O 5 , and MgF 2 may also be used for enhancing the performance of SPR-based sensors and waveguide-based SPR devices [ 102 , 103 , 104 ].…”

The absorption and binding energy of material plays an important role with a large surface area and conductivity for the development of any sensing device. The newly grown 2D nanomaterials like black phosphorus transition metal dichalcogenides (TMDCs) or graphene have excellent properties for sensing devices’ fabrication. This paper summarizes the progress in the area of the 2D nanomaterial-based surface plasmon resonance (SPR) sensor during last decade. The paper also focuses on the structure of Kretschmann configuration, the sensing principle of SPR, its characteristic parameters, application in various fields, and some important recent works related to SPR sensors have also been discussed, based on the present and future scope of this field. The present paper provides a platform for researchers to work in the field of 2D nanomaterial-based SPR sensors.

“…In conventional waveguide-based SPR sensors, the resonant coupling between a surface plasmon and a waveguide mode occurs only for refractive indices of a sample/matrix pair that is considerably higher than the refractive index of aqueous solutions [32]. While various approaches have been undertaken to tackle this problem, ranging from the use of low refractive index glass species [33] or high refractive index overlayers [34] for the fabrication of waveguides to the employment of photonic crystals waveguides [35], a reasonable and efficient application of this coupling architecture for whole-cell SPR biosensors has not been reported so far.…”

Optical sensors based on the excitation of surface plasmons, referred to as surface plasmon resonance (SPR) sensors, have become a central analytical tool for characterizing and quantifying a wide variety of macromolecular interactions, like receptor-ligand contacts. Besides this classical field of application, in the last 15 years, the development of SPR sensors aiming for the detection and analysis of ligand/cell or host/pathogen interactions, cell/ cell contacts, and cellular reactions gained considerable momentum. The number of publications reporting about applications of SPR sensors implementing vital prokaryotic or eukaryotic cells as biorecognition elements for medical diagnostics, environmental monitoring, or biological safety is steadily growing. This review gives a short introduction to the technique of surface plasmon resonance and the parameters that are important for its application in the field of vital cell sensors. Furthermore, the publications concerning the application of such sensors in the analysis of cellular interactions and cellular reactions to extra-and intracellular stimuli are summarized.
