“…Ultraviolet-irradiation techniques have been used to synthesize metal NPs like Ag [5], Au [25], Pd [26] and semi-conductor wires [27] at significantly higher speed compared to conventional thermal convection methods. Recently, El Khoury et al reported that UV-irradiation technique could offers a simple and efficient method for the purification of gold nanorods from excess thiol surfactants in the solution [28] reports for the in situ synthesis of 1-D Ag nanowires by 8 min of UV-photoirradiation on PVA scaffolds in the presence of negatively charged Au seed particles.…”

“…In addition, some functional molecules on the surface of GNPs could work as molecular ''glue'' to assemble nanostructures [89]. Various thiols have been applied to prepare functional GNRs [90][91][92][93]. GNRs assembling in specific patterns, including end-to-end and side-by-side fashions can exhibit unique collective properties which are different from those of both individual GNR and bulk materials [33,94,95].…”

The interplay between liquid crystals and gold nanoparticles, i.e. liquid crystalline gold nanoparticle materials, is challenging as well as fascinating for creating novel functional materials. The resulting hybrid materials hold great promise in many applications such as displays, optics, optoelectronics, sensors, and metamaterials due to their unique properties. In this chapter, the fundamentals of liquid crystals and gold nanoparticles are introduced, and the intriguing progresses of hybrid materials, although in their early stage, are summarized and discussed. These hybrid materials not only could improve device performances, but also the well-organized gold nanoparticles driven by the intrinsic nature of liquid crystal could contribute to the very interesting research topic of the functional metamaterials, i.e. a class of artificial materials having properties that never exist in nature such as unusual electromagnetic properties (e.g. negative refractive index materials for cloaking devices). IntroductionIn modern history, particularly in the recent decades, liquid crystals (LCs) have become a very important class of materials. Since the first invention of LC display (LCD), LCs have become the quintessential materials in information displays such as TVs, computer monitors, and digital displays. In the recent development of LC materials, LCs have moved rapidly beyond display applications and are evolving into entirely new scientific frontiers, opening broad avenues for versatile applications such as lasers, photovoltaics, light-emitting diodes, field effect transistors, biosensors, switchable windows, and nanophotonics [1]. All these applications benefit from LC's unique properties, e.g. self-organization and being able to

“…For the organic thiol monolayer protected anisotropic AuNRs, the solubility, surface chemistry and related properties are dominated by the organic shell. Simple n-alkyl thiols [167], and other functional materials such as photoresponsive azo thiols [168], chiral-azo thiols [169], organic dyes (porphyrin, perylene) [159,160] and polymers terminated with thiols (poly2-(dimethylamino)ethyl methacrylate, poly(acrylic acid), polystyrene) have been used [170].…”

Anisotropic metal nanoparticles with a catalog of promising anisotropic electronic, optical, and chemical properties have been regarded as enabling building blocks in the bottom-up fabrication of functional materials and devices. Specifically, anisotropic gold nanoparticles are currently emerging as fascinating materials due to their unique shape-, size-, and surface-dependent properties. In this chapter, we present the synthesis, properties and applications of different one-, twoand three-dimensional anisotropic gold nanoparticles (AuNPs). The most widely adopted top-down and bottom-up synthesis approaches have been discussed in addition to some of the recently introduced new methods for the fabrication of differently shaped anisotropic AuNPs. The optical property, photothermal effect, surface enhanced Raman scattering, fluorescence enhancement and quenching, surface modification, toxicology, and supramolecular organizations of anisotropic AuNPs have been highlighted. Various practical and potential applications of anisotropic AuNPs in catalysis, sensing, photothermal therapy, drug and gene delivery, and biological and biomedical areas are briefly outlined.
