Journal ArticleDOI
Uptake and Distribution of Ultrasmall Anatase TiO2 Alizarin Red S Nanoconjugates in Arabidopsis thaliana
Jasmina Kurepa,Tatjana Paunesku,Stefan Vogt,Hans Arora,Bryan M. Rabatic,Jinju Lu,M. Beau Wanzer,Gayle E. Woloschak,Jan A. Smalle +8 more
TL;DR: This is the first study describing uptake and distribution of the ultrasmall anatase TiO(2) in the plant model system Arabidopsis by modifying the nanoparticle surface with Alizarin red S and sucrose and demonstrating that nanoconjugates traversed cell walls, entered into plant cells, and accumulated in specific subcellular locations.
Journal ArticleDOI
Imaging of the intracellular topography of copper with a fluorescent sensor and by synchrotron x-ray fluorescence microscopy
Liuchun Yang,Reagan McRae,Maged Henary,Raxit Patel,Barry Lai,Stefan Vogt,Christoph J. Fahrni +6 more
TL;DR: The presented data provide a coherent picture with strong evidence for a kinetically labile copper pool, which is predominantly localized in the mitochondria and the Golgi apparatus.
Journal ArticleDOI
Mechanisms of gold biomineralization in the bacterium Cupriavidus metallidurans
Frank Reith,Barbara Etschmann,Cornelia Grosse,Hugo Moors,Mohammed Abderrafi Benotmane,Pieter Monsieurs,Gregor Grass,Christian J. Doonan,Stefan Vogt,Barry Lai,Gema Martínez-Criado,Graham N. George,Dietrich H. Nies,Max Mergeay,Allan Pring,Gordon Southam,Joël Brugger +16 more
TL;DR: The biomineralization of Au nanoparticles in the metallophillic bacterium Cupriavidus metallidurans CH34 is the result of Au-regulated gene expression leading to the energy-dependent reductive precipitation of toxic Au(III)-complexes.
Journal ArticleDOI
MAPS : A set of software tools for analysis and visualization of 3D X-ray fluorescence data sets
TL;DR: A software package is presented here that implements functions to provide a toolset for the analysis of 3D XRF data sets to improve the photon statistics in such a spectrum.
Journal ArticleDOI
Biology of TiO2-oligonucleotide nanocomposites.
Tatjana Paunesku,Tijana Rajh,Gary P. Wiederrecht,Jörg Maser,Stefan Vogt,Nataša Stojićević,Nataša Stojićević,Miroslava Protic,Barry Lai,Jeremy Oryhon,Marion C. Thurnauer,Gayle E. Woloschak,Gayle E. Woloschak +12 more
TL;DR: The behaviour of 45-Å nanoparticles of titanium dioxide semiconductor combined with oligonucleotide DNA into nanocomposites in vivo and in vitro are described, which possess the chemically and biologically unique new property of a light-inducible nucleic acid endonuclease, which could become a new tool for gene therapy.
