Brake wear (nano)particle characterization and toxicity on airway epithelial cells in vitro
Chloé Puisney, Evdokia K. Oikonomou, Sophie Nowak +4
Particulate air pollution results from different sources, among which those related to road traffic have a significant impact on human health. Combustion-derived particles emitted…
Microrheology of viscoelastic solutions studied by magnetic rotational spectroscopy
Jean-François Berret
Magnetic rotational spectroscopy is based on the use of magnetic micron-size wires for viscosity measurements. Submitted to a rotational magnetic field with increasing frequency, t…
Local viscoelasticity of living cells measured by rotational magnetic spectroscopy
J. -F. Berret
When submitted to a magnetic field, micron size wires with superparamagnetic properties behave as embedded rheometers and represent interesting sensors for micro-rheology. Here we…
Biophysicochemical interaction of a clinical pulmonary surfactant with nano-alumina
F. Mousseau, R. Le Borgne, E. Seyrek +1
We report on the interaction of pulmonary surfactant composed of phospholipids and proteins with nanometric alumina (Al2O3) in the context of lung exposure and nanotoxicity. We stu…
Surfactant-triggered disassembly of electrostatic complexes probed at optical and quartz crystal microbalance length scales
N. Schonbeck, K. Kvale, T. Demarcy +3
A critical advantage of electrostatic assemblies over covalent and crystalline bound materials is that associated structures can be disassembled into their original constituents. N…
Magnetic wire-based sensors for the micro-rheology of complex fluids
L. Chevry, N. K. Sampathkumar, A. Cebers +1
We propose a simple micro-rheology technique to evaluate the viscoelastic properties of complex fluids. The method is based on the use of magnetic wires of a few microns in length…
Versatile Electrostatic Assembly of Nanoparticles & Polyelectrolytes: Coating, Clustering and Layer-by-Layer Processes
J. -P. Chapel, J. -F. Berret
Engineered nanoparticles made from noble metals, rare-earth oxides or semiconductors are emerging as the central constituents of future nanotech developments. In this review, a sur…
The role of the coating and aggregation state in the interactions between iron oxide nanoparticles and 3T3 fibroblasts
Malak Safi, Jean-François Berret
Recent nanotoxicity studies revealed that the physico-chemical characteristics of engineered nanomaterials play an important role in the interactions with living cells. Here, we re…
Nanoparticle aggregation controlled by desalting kinetics
J. Fresnais, C. Lavelle, J. -F. Berret
We report the formation of stable nanoparticle-polymer clusters obtained by electrostatic complexation. The nanoparticles placed under scrutiny are nanoceria (CeO2) coated by short…
Stabilization and Controlled Association of Inorganic Nanoparticles using Block Copolymers
K. Yokota, M. Morvan, J. -F. Berret +1
We report on the structural properties of mixed aggregates made from rare-earth inorganic nanoparticles (radius 20 Angstroms) and polyelectrolyte-neutral block copolymers in aqueou…
Timescales in shear banding of wormlike micelles
O. Radulescu, P. D. Olmsted, J. P. Decruppe +3
We show the existence of three well defined time scales in the dynamics of wormlike micelles after a step between two shear rates on the stress plateau. These time scales are compa…
