WebThe sensing medium, also known as a sensing analyte, is the outermost layer in the proposed SPR biosensor design. There are 2 main SPR geometry configurations: the Kretschmann configuration and Otto’s design. The Kretschmann configuration’s benefits over Otto’s arrangement have made it more widely applicable . The SPR-based … WebOct 5, 2024 · Configurations SPR Instrument design There are several configurations of SPR devices that are capable of generating and measuring surface plasmon resonance …
Optical resonances in Kretschmann and Otto configurations
Webobtained using the Otto configuration. This feature implies that the Otto configuration-based SPR sensor has potential application in multiple gas detection. A comparison be-tween the Otto and Kretschmann configuration can be found in [12]. Table 1 shows the characteristics of the Kretschmann and Otto configurations. (a) (b) Figure 1. WebThe present formulations of the reflectivity allow us to gain insight into physical origins of characteristic behavior of the plasmonic resonances. Attenuated total reflection spectra of planar metal-dielectric structures obtained in the Otto and Kretschmann configurations exhibit resonance dips due to excitation of surface-plasmon polaritons. termites validité

WebNov 15, 2024 · interfaces, Otto and Kretschmann ATR configurations. 1. Introduction Surface plasmon polariton (SPPs) modes supported by metal-dielectric interfaces can be excited using high-index prisms in the attenuated total reflection (ATR) configurations in planar plasmonic structures [1, 2]. The optical properties of surrounding media determine … WebIn practical terms there are two configurations, both based on the ATR technique available to optically excite SPR at the metal/dielectric (or emerging medium) interface. In the first, the Kretschmann configuration, the prism is in direct contact with … WebThe Kretschmann configuration (KC) is one of the first setups, with which surface plasmon polariton (SPP) resonances were observed -6].
