In situ growth synthesis of heterostructured LnPO4–SiO2 (Ln = La, Ce, and Eu) mesoporous materials as supports for small gold particles used in catalytic CO oxidation

31-Oct-2012 | Chengcheng Tian; Song-Hai Chai; Xiang Zhu; Zili Wu; Andrew Binder; J. Chris Bauer; Suree Brwon; Miaofang Chi; Gabrie ..., Journal of Materials Chemistry, 2012

A general in situ growth method was successfully employed to prepare lanthanide phosphate–SiO2 mesostructured cellular foams (MCFs) (LnPO4–MCFs; Ln = La, Ce, and Eu; MCFs = SiO2). These heterostructured MCFs (LnPO4–MCFs) feature binary interpenetrating LnPO4 and silica frameworks, large surface ...


Enhanced protein-mediated binding between oligonucleotide–gold nanoparticle composites and cell surfaces: co-transport of proteins and composites

24-Oct-2012 | Yu Jin Kim; Sang-Mi Ryou; Sudeok Kim; Ji-Hyun Yeom; Min Su Han; Kangseok Lee; Maeng-Je Seong, Journal of Materials Chemistry, 2012

The measurement of the binding force between a cell membrane and an oligonucleotide-functionalized, gold-coated tip using atomic force microscope force spectroscopy showed enhanced binding forces due to the presence of proteins in the buffer. The cellular uptake of oligonucleotide–gold ...


From gold nanorods to nanodumbbells: a different way to tailor surface plasmon resonances by a chemical route

17-Oct-2012 | Peijie Wang; Mingyue Liu; Geli Gao; Shunping Zhang; Honglong Shi; Zhipeng Li; Lisheng Zhang; Yan Fang, Journal of Materials Chemistry, 2012

Spherical ended and arrow ended gold nanodumbbells were synthesized by a simple approach of introducing gold nanorods to solutions of sodium hydroxide and ascorbic acid, respectively. From UV-visible absorption spectroscopy, the transverse and longitudinal surface plasmon resonance that ...


Protein resistant properties of polymers with different branched architecture on a gold surface

04-Oct-2012 | Yuanyuan Zhuang; Qi Zhu; Chunlai Tu; Dali Wang; Jieli Wu; Yumin Xia; Gangsheng Tong; Lin He; Bangshang Zhu; Deyue Ya ..., Journal of Materials Chemistry, 2012

To elucidate the effect of polymeric branched architecture on the protein resistant properties, protein adsorption behaviour of polymers with different branched architecture on a gold surface was investigated. A series of poly((S-(4-vinyl) benzyl S’-propyltrithiocarbonate)-co-(poly(ethylene ...


Anisotropic nanocrystal arrays organized on protein lattices formed by recombinant clathrin fragments

04-Oct-2012 | Nancy Hom; Kinjal R. Mehta; Tsengming Chou; Amy B. Foraker; Frances M. Brodsky; Kent Kirshenbaum; Jin Kim Montclare, Journal of Materials Chemistry, 2012

Recombinant clathrin protein fragments form assemblies that template gold nanocrystals in an array across the latticed surface. The nanocrystals exhibit unusual anisotropic morphologies with long range ordering, both of which are dependent upon the presence of a hexahistidine tag on the clathrin ...


Second Generation Gold Nanobeacons for Robust K-Edge Imaging with Multi-Energy CT

19-Sep-2012 | Dipanjan Pan; Carsten Schirra; Angana Senpan; Ewald Roessl; Axel Thran; Allen J Stacy; Lina Wu; Roland Proksa, Journal of Materials Chemistry, 2012

Spectral CT is the newest advancement in CT imaging technology, which enhances traditional CT images with the capability to image and quantify certain elements based on their distinctive K-edge energies. K-edge imaging feature recognizes high accumulations of targeted elements and presents them ...


Self-Templating Surface-Initiated Polymerization: A Route to Conductive Brushes

22-Aug-2012 | Michał Szuwarzyński; Justyna Kowal; Szczepan Zapotoczny, Journal of Materials Chemistry, 2012

A facile self-templating approach for synthesis of surface-grafted conjugated brushes has been introduced here. Polymeric chains containing acetylene moieties were first grafted from gold surface and then the side groups were polymerized. After doping the obtained brushes exhibited high ...


Specific functionalization of CTAB stabilized anisotropic gold nanoparticles with polypeptides for folding-mediated self-assembly

15-Aug-2012 | Yusong Wang; Daniel Aili; Yee Yan Tay; Robert Selegård; Lars Baltzer; Hua Zhang; Bo Liedberg, Journal of Materials Chemistry, 2012

Anisotropic nanoparticles stabilized by cetyltrimethylammonium bromide (CTAB) are notoriously difficult to homogenously functionalize using conventional gold-thiol chemistry. Using surface assisted laser desorption time of flight mass spectroscopy and scanning transmission electron ...


The electrochemical growth of highly conductive single PEDOT (conducting polymer):BMIPF6 (ionic liquid) nanowires

08-Aug-2012 | Bhuvaneswari Kannan; David E. Williams; Cosmin Laslau; Jadranka Travas-Sejdic, Journal of Materials Chemistry, 2012

A super conductive (2334 S cm−1) single nanowire composed of PEDOT:BMIPF6 in acetonitrile was released between two gold electrodes and the characteristics of the nanowire were measured by scanning ion conductance microscopy and Raman spectroscopy and compared with those grown with PSSA as dopant ...


A Liquid Crystalline Copper Phthalocyanine Derivative for High Performance Organic Thin Film Transistors

08-Aug-2012 | A N Cammidge; Asim Ray; Nandu Chaure; Chandana Pal; Seema Barard; Theo Kreouzis; Isabelle Fernandes (nee Chambrier); ..., Journal of Materials Chemistry, 2012

Bottom-gate, bottom-contact organic thin film transistors (OTFTs) were fabricated using solvent soluble copper 1,4,8,11,15,18,22,25-octakis(hexyl)phthalocyanine as the active semiconductor layer. The compound was deposited as 70 nm thick spin-coated films onto gold source–drain electrodes ...
