This significantly extended second edition addresses the important physical phenomenon of Surface Plasmon Resonance (SPR) or Surface Plasmon Polaritons (SPP) in thin metal films, a phenomenon which is exploited in the design of a large variety of physico-chemical optical sensors. In this treatment, crucial materials aspects for design and optimization of SPR sensors are investigated and described in detail. The text covers a selection of nanometer thin metal films, ranging from free-electron to the platinum-type conductors, along with their combination with a large variety of dielectric substrate materials, and associated individual layer and opto-geometric arrangements. Whereas the first edition treated solely the metal-liquid interface, the SP-resonance conditions considered here are expanded to cover the metal-gas interface in the angular and wavelength interrogation modes, localized and long-range SP's and the influence of native oxidic ad-layers in the case of non-noble metals. Furthermore, a selection of metal grating structures that allow SP excitation is presented, as are features of radiative SP's. Finally, this treatise includes as-yet hardly explored SPR features of selected metal–metal and metal–dielectric superlattices. An in-depth multilayer Fresnel evaluation provides the mathematical tool for this optical analysis, which otherwise relies solely on experimentally determined electro-optical materials parameters.

Nanoelectronics are a diverse set of materials and devices that are so small that quantum mechanics need to be applied to their function. The possibilities these devices present outweigh the difficulties associated with their development, as biosensors and similar devices have the potential to vastly improve our technological reach. The Handbook of Research on Nanoelectronic Sensor Modeling and Applications begins with an introduction of the fundamental concepts of nanoelectronic sensors, then proceeds to outline in great detail the concepts of nanoscale device modeling and nanoquantum fundamentals. Recent advances in the field such as graphene technology are discussed at length in this comprehensive handbook, ideal for electrical engineers, advanced engineering students, researchers, and academics.

SPR is real-time, label-free measurements of binding kinetics and affinity. This has distinct advantage over radioactive or fluorescent labelling methods, in terms of: 1) ligand-analyte binding kinetics, that can be probed without the costly and time-consuming labeling process that may interfere with molecular binding interactions; 2) binding rates and affinity can be measured directly and 3) low affinity interactions in high protein concentrations for can be characterized with less reagent consumption than other equilibrium measurement techniques; 4) Label-free detection of molecular interactions presents an attractive alternative. This is particularly true for protein targets where labels can compromise protein function. Label-free methods are also desirable because they are typically compatible with real-time detection, enabling the determination of rates of association. The success of SPR biosensors was indicated by the growing number of commercially available instruments. Since Biacore AB (originally Pharmacia Biosensor AB) launched the first commercial SPR biosensor on market in 1990, there have been many more competing SPR instruments including IASys (Affinity Sensors), SPR-670 (Nippon Laser Electronics), IBIS (IBIS Technology BV), TISPR (Texas Instruments), etc.
