Metal nanostructures, exploitation

Exploitation of Near-Field Enhancement in Metal Nanostructures. 193... 

On the other hand, silica is often used as an insulating layer when direct communication between different components of a complex systems has to be avoided. For example, for a few years an unprecedented method has been proposed for increasing the efficiency of energy transfer exploiting the effect of plasmonic nanostructures [138-140]. In this systems contact of the fluorophores with the metal (usually silver) must be prevented since it would result in excitation energy dissipation and, most importantly, the increase in the efficiency of the energy transfer can be obtained only if the metal nanostructure is localized at a optimal distance. 

This chapter highlights representative research accomplishments in the area of fundamental and applied studies of the tunable LSPR. Specific applications in the Van Duyne laboratory include exploitation of the LSPR as a signal transduction mechanism for sensing applications and optimization of SERS signals. The optical properties of metallic nanostructures will find future application in the areas of dichroic filters. 

Nanoparticles (NPs), such as nanospheres, nanorods, nanowires, and nanocubes, have attracted extensive attention of material scientists because of their application in many areas of fundamental and technical importance. For example, they can be used to experimentally probe the effects of quantum confinement on electronic, optic, and other related properties [1-3]. They have also been widely exploited for use in manufacturing electronic, photonic, and sensing devices [4-6]. The intrinsic properties of a metal NP are mainly determined by its composition, size, and shape [7]. For studying size- and shape-dependent properties, it is highly desirable to synthesize metal nanostructures with well-controlled size and shape [8]. 

Similar monolayers have been prepared with a diversity of electroactive units with the ultimate goal of elucidating the subtle balance between the structural and the electronic factors that regulate interfacial electron transfer.5,9,10 In particular, these studies have focused their attention on the rationalization of the influence that the distance between the electrode surface and the redox centers as well as the nature of the linkers between them have on the rates of electron transfer. In parallel to these fundamental investigations, the ability of thiols to anchor electroactive units on metallic electrodes has also been exploited to fabricate a wealth of nanostructured materials with tailored functions and properties.6-8 Indeed, these convenient building... 

Plasmonic en neering provides the flmdamentals for nanostructure fabrication exploiting the unique optical propolies of certain metals (mainly silver and gold) and advancing the development and applications of plasmon enhanced luminescence. Nanostructures can not only be fabricated to provide enhancement throughout the UV-Vis spectrum but also for near infiared excitation and emissions.
