Journal ArticleDOI
Size-Dependent Cytotoxicity of Gold Nanoparticles
Yu Pan,Sabine Neuss,Annika Leifert,Monika Fischler,Fei Wen,Ulrich Simon,Günter Schmid,Wolfgang Brandau,Willi Jahnen-Dechent +8 more
TL;DR: A systematic study of water-soluble gold nanoparticles stabilized by triphenylphosphine derivatives ranging in size from 0.8 to 15 nm is made and the cytotoxicity of these particles in four cell lines representing major functional cell types with barrier and phagocyte function are tested.
Journal ArticleDOI
Chain-like assembly of gold nanoparticles on artificial DNA templates via ‘click chemistry’
Monika Fischler,Alla S. Sologubenko,Joachim Mayer,Guido H. Clever,Glenn A. Burley,Johannes Gierlich,Thomas Carell,Ulrich Simon +7 more
TL;DR: A new type of azide-functionalized gold nanoparticle and their coupling to an alkyne-modified DNA duplex using the copper(I)-catalyzed Huisgen cycloaddition ('click chemistry'), resulting in a chain-like assembly of nanoparticles on the DNA template.
Journal ArticleDOI
Formation of bimetallic Ag-Au nanowires by metallization of artificial DNA duplexes.
Monika Fischler,Ulrich Simon,Hadar Nir,Yoav Eichen,Glenn A. Burley,Johannes Gierlich,Philipp M. E. Gramlich,Thomas Carell +7 more
TL;DR: Uniform bimetallic nanowires, tunable in size, have been grown on artificial DNA templates via a two-step metallization process, resulting in the high selectivity of the process, due to the exact spatial control of modified DNA base incorporation and hence the confinement of meetallization centers at addressable sites.
Journal ArticleDOI
Controlled nucleation of DNA metallization
Christian T. Wirges,Jan Timper,Monika Fischler,Alla S. Sologubenko,Joachim Mayer,Ulrich Simon,Thomas Carell +6 more
TL;DR: Novel procedures aimed at increasing the selectivity of the metallization process are the decoration of DNA with functional groups to control the spatial distribution of the nucleation sites, the photochemical deposition of silver on DNA strands, and the formation of DNA–Pt adducts as precursors for metal deposition on DNA.
Journal ArticleDOI
Ordered arrays of silicon pillars with controlled height and aspect ratio
Alexander Sinitskii,Alexander Sinitskii,Stefan Neumeier,Jürgen Nelles,Monika Fischler,Ulrich Simon +5 more
TL;DR: In this paper, the fabrication of ordered arrays of silicon pillars via a combination of nanosphere lithography (NSL) and reactive ion etching (RIE) is described.
