“…Gold nanorod structures have been produced using both EBL [100,198,199] and FIB techniques. [100,200,201] Figure 12, taken from the work of Billot et al, [198] shows scanning electron microscopy (SEM) images of arrays of gold nanorods fabricated to study the effect of nanorod length on the surface-enhanced plasmon resonances originating from these structures.…”

Noble metal nanoparticles are capable of confining resonant photons in such a manner as to induce coherent surface plasmon oscillation of their conduction band electrons, a phenomenon leading to two important properties. Firstly, the confinement of the photon to the nanoparticle's dimensions leads to a large increase in its electromagnetic field and consequently great enhancement of all the nanoparticle's radiative properties, such as absorption and scattering. Moreover, by confining the photon's wavelength to the nanoparticle's small dimensions, there exists enhanced imaging resolving powers, which extend well below the diffraction limit, a property of considerable importance in potential device applications. Secondly, the strongly absorbed light by the nanoparticles is followed by a rapid dephasing of the coherent electron motion in tandem with an equally rapid energy transfer to the lattice, a process integral to the technologically relevant photothermal properties of plasmonic nanoparticles. Of all the possible nanoparticle shapes, gold nanorods are especially intriguing as they offer strong plasmonic fields while exhibiting excellent tunability and biocompatibility. We begin this review of gold nanorods by summarizing their radiative and nonradiative properties. Their various synthetic methods are then outlined with an emphasis on the seed-mediated chemical growth. In particular, we describe nanorod spontaneous self-assembly, chemically driven assembly, and polymer-based alignment. The final section details current studies aimed at applications in the biological and biomedical fields.

“…The nanostructures are deposited on a CaF 2 substrate through electron beam lithography (EBL) and lift-off techniques. To achieve EBL, a 30 kV Hitachi S-3500N scanning electron microscope (SEM) equipped with nanometer pattern generation system (NPGS, by J.C. Nabity) are used [8]. The SEM images [20,21,23,37] reveal the experimental sources of uncertainties on the geometrical parameters in the process of fabrication:…”

“…Of special interest is the huge nearfield enhancement at resonance because it enables extraordinarily sensitive detection of molecules. [1][2][3][4][5][6][7] The exact frequency of the plasmonic resonance depends not only on the kind of metal ͑described by the plasma wavelength P ͒ but also on length L, diameter D ͑or the spatial cross section͒, and overall shape of the particle. [8][9][10][11][12] Considering a cylindrical antenna with L Ͼ D and with very good metallic conductivity, the relation between L and the fundamental optical resonance wavelength res is well described by the linear relation, 11 2L = n 1 + n 2 res / P .…”
