Gold nanorods

In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

Gold nanorods (AuNRs) are suitable for constructing self-assembled structures for the development of biosensing devices and are usually obtained in the presence of cetyltrimethylammonium bromide (CTAB).

In this study, ZnO nanorods decorated with gold (Au) nanoparticles with the desired size parameters were fabricated using a simple, low-cost, and highly efficient method. The ZnO nanorod structure was fabricated using a hydrothermal method on a ZnO seed layer with hydrothermal solution concentrations varying from 20 mM to 90 mM.

Iron oxide nanorods were synthesized by chemical co-precipitation method. The structural and morphological characteristics of the as-synthesized nanorods were analyzed by Xray diffraction (XRD) and scanning electron microscopy. The results show that the iron oxide nanorods include the mixture of Fe3O4, γ-Fe2O3 and FeOOH with the diameter and the length of iron oxide nanorods to be 30 and 100 nm, respectively. The iron oxide nanorods were then dispersed and deposited on the gold electrode of quartz crystal microbalance (QCM) for the gas sensor.

In this paper, the gold nanorods (GNRs) were synthesized via a seed-mediated method by using 1-3 nm seeds-in diameter and gold atoms created from the reduced Au3+ ions by ascorbic acid (AA) in the presence of cetyltrimethyl ammonnium bromide (CTAB) as a soft template. The aspect ratio of GNRs as well as growth yield were controlled by adjusting the concentration of Ag+ ions.

We aimed to evaluate the photothermal effects of gold nanorods (GNRs) modified with antiepidermal growth factor receptor (EGFR) monoclonal antibody (mAb) on laryngeal cancer cells. EGFR protein expressions in HEP-2 cells, and normal laryngeal epithelial and laryngeal cancer tissues were detected by western blot.

The results show that the AuNPs exhibited a single plasmonic resonance, the AuNRs displayed two identical and separated modes of the resonance, and the random Au nano-islands presented a very broad resonance. Specifically, tailoring the anisotropy of the Au nanorods enabled extending their resonant frequencies from the visible to the near infrared region, which is in accordance with the finite different time domain simulations.

Nano, a word derived from the Greek wordνανoς(nanos, which translated denotes “dwarf”), is nowadays a synonym for a whole research area—the nanosciences. One area within this huge research field is nano-optics, where the response of a nanoparticle to an incoming light wave is investigated. In detail, nanoparticles made of noble metals evoke a special interest, since these particles show a strong response to the incoming light wave. This attribute can be explained by the effect that the mentioned light wave excites the electrons in the conduction band to a collective oscillation.
