  • The tunability of the optical properties of small gold nanoparticles assembled from size-selected Au{sub 6-10} clusters on the surface of indium-tin-oxide glass support was studied as a function of gold particle size and shape using UV-VIS and dark-field microscopy techniques. The size and shape of gold nanoparticles was determined by employing synchrotron X-ray scattering. The obtained spectra show that a 350 nm wavelength range is accessible by proper tuning the size and shape of the studied nanoparticles with 1-2.5 nm main size and asymmetric vs symmetric form.
  • A systematic investigation into the relationship between the solid-state luminescence and the intermolecular Au∙∙∙Au interactions in a series of pyrazolate-based gold(I) trimers; tris(μ 2-pyrazolato-N,N')-tri-gold(I) (1), tris(μ 2-3,4,5-trimethylpyrazolato-N,N')-tri-gold(I) (2), tris(μ 2-3-methyl-5-phenylpyrazolato-N,N')-tri-gold(I) (3) and tris(μ 2-3,5-diphenylpyrazolato-N,N')-tri-gold(I) (4) has been carried out using variable temperature and high pressure X-ray crystallography, solid-state emission spectroscopy, Raman spectroscopy and computational techniques. Single-crystal X-ray studies show that there is a significant reduction in the intertrimer Au∙∙∙Au distances both with decreasing temperature and increasing pressure. In the four complexes, the reduction in temperature from 293 to 100 K is accompanied by a reduction in the shortest intermolecular Au∙∙∙Aumore » contacts of between 0.04 and 0.08 Å. The solid-state luminescent emission spectra of 1 and 2 display a red shift with decreasing temperature or increasing pressure. Compound 3 does not emit under ambient conditions but displays increasingly red-shifted luminescence upon cooling or compression. Compound 4 remains emissionless, consistent with the absence of intermolecular Au∙∙∙Au interactions. The largest pressure induced shift in emission is observed in 2 with a red shift of approximately 630 cm -1 per GPa between ambient and 3.80 GPa. The shifts in all the complexes can be correlated with changes in Au∙∙∙Au distance observed by diffraction.« less
  • Gold nanoparticles (GNPs) have gained considerable attention for application in science and industry. However, the untoward effects of such particles on female fertility remain unclear. The objectives of this study were to (1) examine the effects of 10-nm GNPs on progesterone and estradiol-17b accumulation by rat ovaries ex vivo and (2) to identify the locus/loci whereby GNPs modulate steroidogenesis via multiple-reference gene quantitative real-time RT-PCR. Regression analyses indicated a positive relationship between both Star (p < 0.05, r2 = 0.278) and Cyp11a1 (p < 0.001, r2 = 0.366) expression and P4 accumulation. upon exposure to 1.43 * 106 GNPs/mL. Additionalmore » analyses showed that E2 accumulation was positively associated with Hsd3b1 (p < 0.05, r2 = 0.181) and Cyp17a1 (p < 0.01, r2 = 0.301) expression upon exposure to 1.43 * 13 and 1.43 * 109 GNPs/mL, respectively. These results suggest a subtle treatmentdependent impact of low-dose GNPs on the relationship between progesterone or estradiol-17b and specific steroidogenic target genes, independent of oxidative stress or inhibin.« less
  • Solutions containing KAu(CN){sub 2} ({approximately}5 {times} 10{sup {minus}4} M) methanol (0.3 M), and nitrous oxide (2.5 {times} 10{sup {minus}2} M) are {gamma}-irradiated in the presence of colloidal gold ({approximately}6 {times} 10{sup {minus}5} M; mean particle size, 15 nm). The hydroxymethyl radicals, {sup {sm_bullet}}CH{sub 2}OH, which are generated in these solutions, reduce Au(I) in Au(CN){sub 2}{sup {minus}}, and the reduced gold is completely deposited on the gold seeds to yield larger particles. The particle growth is followed spectrophotometrically and by electron microscopy. A mechanism is proposed in which the radicals transfer electrons to the gold particles and Au(CN){sub 2}{sup {minus}} ismore » subsequently reduced by the stored electrons directly at the surface of the particles. In further steps of particle enlargement, Au(CN){sub 2}{sup {minus}} is reduced in solutions in which the gold particles synthesized in the preceding step serve as seeds, the result being larger and larger gold particles up to 120 nm. The reduction yield is discussed with respect to side reactions of the radicals, such as mutual deactivation and gold-catalyzed H{sub 2} formation. The radiation chemical method makes it possible to enlarge gold particles to any desired size. The reduction of Au(CN){sub 2}{sup {minus}} in the absence of seeds is also described.« less
  • Size-controlled synthesis of nanoparticles of less than a few nanometers in size is a challenge due to the spatial resolution limit of most scattering and imaging techniques used for their structural characterization. We present the self-consistent analysis of the extended x-ray absorption fine-structure (EXAFS) spectroscopy data of ligand-stabilized metal nanoclusters. Our method employs the coordination number truncation and the surface tension models in order to measure the average diameter and analyze the structure of the nanoparticles. EXAFS analysis was performed on the two series of dodecanethiol-stabilized gold nanoparticles prepared by one-phase and two-phase syntheses where the only control parameter wasmore » the gold/thiol ratio x, varied between 6:1 and 1:6. The two-phase synthesis resulted in the smaller particles whose size decreased monotonically and stabilized at 16 Angstroms when x was lowered below 1:1. This behavior is consistent with the theoretically predicted thermodynamic limit obtained previously in the framework of the spherical drop model of Au nanoparticles.« less
