ZnO nanorods decorated with Au nanoparticles applied as gas sensors

Gasparotto G., Mazon T., Gasparotto G., Silva R.A., Zaghete M.A., Perazolli L.A., Varela J.A., CTI, BR

Zinc oxide (ZnO) is a n-type semiconductor with energy band gap of 3:37 eV and a large binding energy of 60 meV at room temperature. ZnO nanostructures can be easily obtained with different morphologies by [...]

Au nanoparticles decorated hydrothermally processed rutile TiO2 nanorods for photoelectrochemical water splitting

Sun B., Shi T., Sheng W., Jiang T., Liao G., Huazhong University of Science and Technology, CN

In this work, we investigate the synthesis of single crystalline rutile TiO2 nanorods for photoelectrochemical water splitting. A facile and convenient hydrothermal method was used to fabricate it. We realize the control of the length, [...]

Enhancement of Ferromagnetism in Amine/Organic Acid Capped Au-Nanoparticles by Yttrium-Oxide Inclusion

Lesseux G.G., Iwamoto W., Rosas V.H., Vautier-Giongo C., Rettori C., Rettori D., Urbano R.R., Rettori C., Rettori D., Universidade Estadual de Campinas (UNICAMP), BR

In this work we report on the enhancement of the ferromagnetism of amine/organic acid capped Au nanoparticles (AuNPs) by incorporation of yttrium-oxide (Y2O3). The magnetization measurements displayed a ferromagnetic (FM) loop with a coercive field [...]

Ferromagnetic Resonance in amine/organic acid caped Au-nanoparticles assisted by rare-earths oxides

Lesseux G.G., Iwamoto W., Rosas V.H., Vautier-Giongo C., Rettori C., Rettori D., Rettori C., Rettori D., Universidade Estadual de campinas, BR

Amine/organic acid caped Au-nanoparticles (Au-NPs) were prepared by reducing gold tetrachloroaurate (HAuCl4.3H2O) and rare-earth (RE)-oxides (RE = Er and Y and monodisperse samples of caped Au-NPs of ~10 nm in diameter were obtained. The magnetization [...]

Labile Catalytic Packaging and Delivering of Short Interference RNA to Cancer Cells: Control of Gold Nanoparticles “out” of RNA Complexes

Chen A.M., Taratula O., Wei D., Minko T., He H., Rutgers, The State of New Jersey, US

We report a novel approach to efficiently package and deliver siRNAs with low generation dendrimers by using Au nanoparticles as a “labile catalytic” packaging agent. The Au nanoparticles helped low generation dendrimers to package siRNA [...]

Nanostructures fabrication via self-assembly of hybrid block copolymer/nanoparticles in thin film

Fahmi A., Gindy N., University of Nottingham, UK

Fabrication of Nanostructures via self-assembly process is an elegant concept for the production the next generation of miniaturised devices. However, many challenges need to be overcome in 2D and 3D nanofabrication before the routine utilisation [...]

Label Free Colorimetric Detection of Single Nucleotide Polymorphisms in Pcr Amplified Genomic DNA

Li H.X., Rothberg L.J., University of Rochester, US

Analysis of DNA is increasingly important in clinical diagnosis, pathology and genetics1, 2. Single nucleotide polymorphisms (SNPs) in genomic DNA are known to be responsible for a number of hereditary conditions3 and cancers4. Nearly all [...]

Rapid DNA Sequence Identification based on Electrostatic Interactions with Unmodified Gold Nanoparticles

Li H.X., Rothberg L.J., University of Rochester, US

Sequence-specific detection of DNA play more and more important role in clinical diagnosis and molecular biology research. Most assays identify specific sequence through hybridization of an immobilized probe to the target analyte after the latter [...]
