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.

Spontaneous Assembly of Miktoarm Stars into Vesicular Interpolyelectrolyte Complexes
Felix A. Plamper,Arjan P. H. Gelissen,Jan Timper,Andrea Wolf,Alexander B. Zezin,Walter Richtering,Heikki Tenhu,Ulrich Simon,Joachim Mayer,Oleg V. Borisov,Dmitry V. Pergushov +10 more
TL;DR: The transmission electron microscopy of vitrified samples (cryogenic TEM) is compared with the samples at ambient conditions (in situ TEM), giving one of the first TEM reports on soft matter in its pristine environment.

Multidentate thioether ligands coating gold nanoparticles.
TL;DR: The design and synthesis of oligomeric ligands based on benzylic thioethers are presented together with their ability to enwrap and stabilize gold nanoparticles with diameters below 2 nm, which become--with increasing length of the oligomer--more monodisperse and stable.

Gesteuerte Keimbildung bei der DNA-Metallisierung†
Christian T. Wirges,Jan Timper,Monika Fischler,Alla S. Sologubenko,Joachim Mayer,Ulrich Simon,Thomas Carell +6 more
TL;DR: The meisten Verfahren zur Metallisierung von DNA beruhen darauf, dass elektrostatisch an DNA gebundene Metallionen durch Zugabe eines Reduktionsmittels in Metallcluster uberfuhrt werden, die an der DNA haften.

Size-dependent multispectral photoacoustic response of solid and hollow gold nanoparticles
Benjamin S. Gutrath,Martin F. Beckmann,Anne Buchkremer,Thomas Eckert,Jan Timper,Annika Leifert,Walter Richtering,Georg Schmitz,Ulrich Simon +8 more
TL;DR: The molar PA intensity of 1.0 nm AuNPs was comparable to the commonly used organic dye methylene blue, and rapidly increased with the lateral size of AuN Ps, according to the diode laser set-up.
