“…An affinity biosensor consists of a transducer (electrochemical [1], piezoelectric [2], or optical [3]) and a biological recognition element which is able to interact with a selected analyte. Various optical methods have been exploited in biosensors including fluorescence spectroscopy [4], interferometry (reflectometric white light interferometry [5] and modal interferometry in optical waveguide structures [6]), spectroscopy of guided modes of optical waveguides (grating coupler [7] and resonant mirror [8]), and surface plasmon resonance (SPR) [9,10].…”

Surface plasmon resonance (SPR) biosensors are optical sensors exploiting special electromagnetic waves-surface plasmon-polaritons-to probe interactions between an analyte in solution and a biomolecular recognition element immobilized on the SPR sensor surface. Major application areas include detection of biological analytes and analysis of biomolecular interactions where SPR biosensors provide benefits of label-free real-time analytical technology. This paper reviews fundamentals of SPR affinity biosensors and discusses recent advances in development and applications of SPR biosensors.

“…This class of sensors is of major importance in biomedical analysis and they are quite flexible to miniaturization. In potentiometric sensors the potential change due to the accumulation of charge (electrons) on the working electrode is measured relative to a reference electrode when no current is flowing (Gauglitz, 1996). The working electrode potential must depend on the concentration of the analyte in the solution.…”
