“…This process combines the formation of a soft LC phase with electrodeposition, which is fast, reproducible, inexpensive and versatile for the fabrication of metal nanowire arrays with high density and large aspect ratio. In addition, the Ag ribbons consisting of close-packed Ag nanoparticles were prepared in lamellar LLCs [97]. Yan et al demonstrated that Cu 2 O nanowires (figures 5 and 6) with high aspect ratio could be readily electrodeposited from reverse hexagonal LLC phases.…”

This review introduces and summarizes lyotropic liquid crystal (LLC) directed syntheses of nanostructured materials consisting of porous nanostructures and zero-dimensional (0-D), one-dimensional (1-D) and two-dimensional (2-D) nanostructures. After a brief introduction to the liquid crystals, the LLCs used to prepare mesoporous materials are discussed; in particular, recent advances in controlling mesostructures are summarized. The LLC templates directing the syntheses of nanoparticles, nanorods, nanowires and nanoplates are also presented. Finally, future development in this field is discussed.

“…8 Of the various strategies used, chemical reduction has proved to be an ideal strategy for the generation of uniform nanoparticles with a narrow size distribution via microemulsion, 9 coprecipitation, 10 carbon nanotube, 11 and polymer protection methods. [12][13][14] Biological macromolecules, 15,16 block copolymers, 17,18 dendrimers, 19,20 liquid crystals, 21 latex particles, 22 mesoporous inorganic materials, 5,23 microgels, 24 and hydrogels 25,26 have been used as templates for the production of well-dispersed nanoparticles. Metal nanoparticles have been extensively studied for many years because they usually exhibit unique properties and can be potentially used in many applications, including optics, 1 catalysis, 2 biodiagnostics, 3 and surfaceenhanced Raman scattering.…”

This article presents the findings of a facile and effective nanoparticle synthesis approach based on aqueous solutions of gum acacia (GA), also known as gum arabic without the addition of any toxic reagents either for the reduction or capping for the effective stabilization of palladium (Pd) nanoparticles with a narrow size distribution (with a H 2 PdCl 4 /GA ratio of 1:29.411, the solution the average diameter was 9.1 nm, and the standard deviation was 60.3 nm). In this approach, the particle size was controlled by the manipulation of the temperature, time, and concentration of GA. The synthesized Pd nanoparticles were well characterized by ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, dynamic light scattering, and thermogravimetric analysis. This route was very simple and reproducible, and further study on the application of these nanoparticles for various organic transformations is underway.

We report a facile approach for the spontaneous formation of silver nanoparticles in the presence of gum acacia polymer (a natural polymer) without the addition of any typical reducing agent under mild conditions. Silver nanoparticles ($ 5 nm) have been obtained by the mixing of equal amounts of 0.5 wt % aqueous solutions of acacia and silver nitrate. The formation of silver nanoparticles has been confirmed with ultraviolet-visible, Fourier transform infrared, X-ray diffraction, and X-ray photoelectron spectroscopy analyses. Gum acacia polymeric chains promote the reduction process and act as good stabilizers over 5 months. To confirm the formation and stabilization of the nanoparticles, a transmission electron microscope has been employed. The advantage of this methodology is that it is possible to prepare silver nanoparticles without any organic solvents or reducing agents.
