Charge transfer across C-H center dot center dot center dot O hydrogen bonds stabilizes oil droplets in water

Sylvie Roke, Saranya Pullanchery Sankara Narayanan, Sergey Kulik, Benjamin Rehl

The hydrophobic-water interface plays a key role in biological interactions. However, both the hydrophobic-water interfacial molecular structure and the origin of the negative zeta potential of hydrophobic droplets in water are heavily contested. We report ...

Interactions of Tris with rutile surfaces and consequences for in vitro bioactivity testing

Paul Bowen, Ulrich Aschauer

Tris(hydroxymethyl)aminomethane (Tris) has been used as the buffer in bioactivity testing for over two decades and has become a standard choice for the scientific community. While it is believed to be non-interacting, the extent of its interactions with ti ...

In-situ Investigations on Gold Nanoparticles Stabilization Mechanisms in Biological Environments Containing HSA

Francesco Stellacci, Antonia Neels, Quy Ong Khac, Marianne Liebi

Nanoparticles (NPs) developments advance innovative biomedical applications. However, complex interactions and the low colloidal stability of NPs in biological media restrict their widespread utilization. The influence of NPs properties on the colloidal st ...

Vascular-targeted micelles as a specific MRI contrast agent for molecular imaging of fibrin clots and cancer cells

Anne-Sophie Chauvin, Aurélien Thomas, Vassily Vorobiev

Molecular medical imaging is intended to increase the accuracy of diagnosis, particularly in cardiovascular and cancer-related diseases, where early detection could significantly increase the treatment success rate. In this study, we present mixed micelles ...

Imaging Cu2+ binding to charged phospholipid membranes by high-throughput second harmonic wide-field microscopy

Sylvie Roke, David Roesel, Seonwoo Lee

The interaction of divalent copper ions (Cu2+) with cell membranes is crucial for a variety of physiological processes of cells, such as hormone synthesis and cellular energy production. These interactions would not be possible without membrane hydration. ...

On the stability and necessary electrophoretic mobility of bare oil nanodroplets in water

Sylvie Roke, Saranya Pullanchery Sankara Narayanan, Halil Ibrahim Okur, Hilton Barbosa De Aguiar, Sergey Kulik

Hydrophobic oil droplets, particles, and air bubbles can be dispersed in water as kinetically stabilized dispersions. It has been established since the 19th century that such objects harbor a negative electrostatic potential roughly twice larger than the t ...

Self-Propulsion of Active Colloids via Ion Release: Theory and Experiments

Ignacio Pagonabarraga Mora, Samuel Sanchez

We study the self-propulsion of a charged colloidal particle that releases ionic species using theory and experiments. We relax the assumptions of thin Debye length and weak nonequilibrium effects assumed in classical phoretic models. This leads to a numbe ...

Inkjet-Printed Carbon Nanotube Electrodes Modified with Dimer-captosuccinic Acid-Capped Fe3O4 Nanoparticles on Reduced Graphene Oxide Nanosheets for Single-Drop Determination of Trifluoperazine

Hubert Girault, Andreas Stephan Lesch, Milica Jovic

Here we report the design of a disposable single-drop voltammetric sensor for the quantitative determination of antipsy-chotic drug trifluoperazine (TFP). The sensor was build using inkjet-printed carbon nanotube (CNT) electrodes which were modified with d ...

Electrosorption at metal surfaces from first principles

Nicola Marzari

Electrosorption of solvated species at metal electrodes is a most fundamental class of processes in interfacial electrochemistry. Here, we use its sensitive dependence on the electric double layer to assess the performance of ab initio thermodynamics appro ...
