In this study, gold (Au) nanowires were synthesized with a modified hydrothermal process, and high structural purity and control over Au nanowire diameter were achieved. Parametric study was performed to examine the effect of surfactant concentration, reaction time, and temperature on the quality of the synthesized products. The optimum conditions were determined for the synthesis with two different surfactant molecules, namely hexamethylenetetramine and ethylenediaminetetraacetic acid. Au nanowires synthesized under optimum conditions have high aspect ratio (diameters in the range of 50-110 nm and lengths in micrometers) with high structural purity and are potentially useful for applications such as surface-enhanced Raman scattering spectroscopy and transparent conducting electrodes for optoelectronic devices.

Gold nanostar @ iron oxide core-shell nanostructures: synthesis, characterization, and demonstrated surface-enhanced Raman scattering properties Nalbant Esentürk, Emren (2013-01-01) Iron oxide-coated gold nanostars are produced by first synthesizing gold nanostars (ca 150 nm), then introducing a polyvinylpyrollidone coating followed by reducing iron(II) and iron(III) salts on the nanoparticle (NP) surface. Morphological and chemical composition characterizations of these composite nanomaterials were performed via field-emission transmission electron microscopy/energy dispersive spectroscopy studies. The analysis revealed that the majority of the NPs had coating of approximately 1-5 nm ...
TiN(IV) oxide coated gold nanoparticles: synthesis, characterization and investigation of surface enhanced raman scattering activities Elçi, Aylin; Nalbant Esentürk, Emren; Department of Chemistry (2017) Noble metal nanoparticles (i.e. gold (Au) and silver (Ag)) have received enormous attention due to their superior optical properties related to localized surface plasmon resonance (LSPR) and their potential applications in sensing, imaging, catalysis and optoelectronic devices. In particular, the ones with anisotropic morphologies have attracted intense interest from the researchers because of their superior optoelectronic properties. High electromagnetic field forms on the nanoparticle surface. The intensi...
Gold nanoparticle modified conducting polymer of 4-(2,5-di(thiophen-2-yl)-1H-pyrrole-1-l) benzenamine for potential use as a biosensing material Tuncagil, Sevinc; Ozdemir, Caglar; ODACI DEMİRKOL, DİLEK; TİMUR, SUNA; Toppare, Levent Kamil (2011-08-01) Gold nanoparticle (AuNP) modified conducting polymer of 4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)benzenamine (SNS-NH2) was used as the biosensing platform for glucose analysis. Electrochemical measurements were carried out by following the consumed oxygen due to the enzymatic reaction of glucose oxidase (GOx) at -0.7 V vs Ag/AgCl. Optimisation of pH, enzyme loading, stability experiments were carried out. Effect of NP was investigated by monitoring the signal responses at different AuNP sizes and amounts. A ...
Biological and green synthesis of silver nanoparticles Forough, Mehrdad; Khalil, Farhadi (2010-12-01) In this work, the synthesis of stable silver nanoparticles by the bioreduction method was investigated. Aqueous extracts of the manna of hedysarum plant and the soap-root (Acanthe phylum bracteatum) plant were used as reducing and stabilizing agents, respectively. UV-Vis absorption spectroscopy was used to monitor the quantitative formation of silver nanoparticles. The characteristics of the obtained silver nanoparticles were studied using X-ray diffraction analysis (XRD), energy-dispersive spectroscopy (ED...
Polyol Synthesis of Silver Nanowires: An Extensive Parametric Study Coskun, Sahin; Aksoy, Burcu; Ünalan, Hüsnü Emrah (2011-11-01) Silver nanowires have been synthesized by a polyol process. A detailed parametric study determining the relationship between final morphology of the products and,temperature, injection rate, molar ratio of poly(vinylpyrrolidone) to silver nitrate, sodium chloride amount, and stirring rate is presented. The as-synthesized silver nanowires are analyzed by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The dependency of nano-wire morphology and aspect ra...
