Physical vapour deposition of cyanine salts and their first application in organic electronic devices
Frank Nüesch, Jakob Heier, Antonia Neels, Léo Duchêne, Donatas Gesevicius
A symmetrical trimethine indocyanine dye chromophore was modified with the bistriflylimide anion to study the changes in Coulomb interactions, thermal stability and the volatility of the organic salt. The bulky bistriflylimide anion minimizes electrostatic ...
2019Two dimensional diffusion-controlled triplet–triplet annihilation kinetics
Hubert Girault, Astrid Johana Olaya Avendano, Pierre-François Marie Brevet, Grégoire Clément Gschwend, Morgan Kazmierczak
Diffusion controlled chemical reactions are usually observed in three dimensionalmedia. In contrast, planar bimolecular reactions taking place between reagents adsorbed at a soft interface are two-dimensional and therefore cannot be studied within the same ...
2019Superweak Coordinating Anion as Superstrong Enhancer of Cyanine Organic Semiconductor Properties
Frank Nüesch, Jakob Heier, Antonia Neels, Donatas Gesevicius
The superweak tetrakis(nonafluoro-tert-butoxy)aluminate coordinating anion was employed to introduce pseudo-gas-phase conditions to the 2-[5-(1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)-1,3-pentadien-1-yl]-1,3,3-trimethyl-3H-indolium chromophore. The r ...
2018Nanoplasmonic mid-infrared biosensor for in vitro protein secondary structure detection
Giovanni Dietler, Hilal Lashuel, Hatice Altug, Francesco Simone Ruggeri, Dordaneh Etezadi, John Blaine Warner IV
Plasmonic nanoantennas offer new applications in mid-infrared (mid-IR) absorption spectroscopy with ultrasensitive detection of structural signatures of biomolecules, such as proteins, due to their strong resonant near-fields. The amide I fingerprint of a ...
Springer Nature2017Fluorinated and Charged Hydrogenated Alkanethiolates Grafted on Gold: Expanding the Diversity of Mixed-Monolayer Nanoparticles for Biological Applications
Low intrinsic toxicity, high solubility, and stability are important and necessary features of gold nanoparticles to be used in the biomedical field. In this context, charged nanoparticles proved to be very versatile, and among them charged mixed-monolayer ...
American Chemical Society2017Optical label-free and model-free probe of the surface potential of nanoscale and microscopic objects in aqueous solution
Sylvie Roke, Cornelis Ulrich Lütgebaucks
The electrostatic environment of aqueous systems is an essential ingredient for the function of any living system. To understand the electrostatic properties and their molecular foundation in soft, living, and three-dimensional systems, we developed a tabl ...
Amer Physical Soc2016Hematite photoelectrodes for water splitting: evaluation of the role of film thickness by impedance spectroscopy
Kevin Sivula, Florian Le Formal
The electrochemical behavior of alpha-Fe2O3 photoelectrodes prepared by spray pyrolysis with different thicknesses was examined under dark and illumination conditions. The main charge transport phenomena occurring in the PEC cell photoelectrodes were chara ...
Royal Soc Chemistry2014Measurement of the Position-Dependent Electrophoretic Force on DNA in a Glass Nanocapillary
Aleksandra Radenovic, Lorenz Jan Steinbock, Roman Bulushev, Sergey Khlybov
The electrophoretic force on a single DNA molecule inside a glass nanocapillary depends on the opening size and varies with the distance along the symmetrical axis of the nanocapillary. Using optical tweezers and DNA-coated beads, we measured the stalling ...
American Chemical Society2014Diffusion-limited reactions in crowded environments: a local density approximation
Paolo De Los Rios, Nicolas Dorsaz, Giuseppe Foffi, Francesco Piazza
In the real world, diffusion-limited reactions in chemistry and biology mostly occur in crowded environments, such as macromolecular complex formation in the cell. Despite the paramount importance of such phenomena, theoretical approaches still mainly rely ...
Iop Publishing Ltd2013Colloidal Stability of Self-Assembled Mono layer-Coated Gold Nanoparticles: The Effects of Surface Compositional and Structural Heterogeneity
Francesco Stellacci, Randy Patrick Carney
Surface heterogeneity plays an important role in controlling colloidal phenomena. This study investigated the self-aggregation and bacterial adsorption of self-assembled monolayer coated gold nanoparticles (AuNPs) with different surface compositional and s ...
