In vitro toxicity of nanoceria: effect of coating and stability in biofluids
N. Ould-Moussa, M. Safi, M. A. Guedeau-Boudeville +3
Due to the increasing use of nanometric cerium oxide in applications, concerns about the toxicity of these particles have been raised and have resulted in a large number of investi…
Interactions between Magnetic Nanowires and Living Cells : Uptake, Toxicity and Degradation
Malak Safi, Minhao Yan, Marie-Alice Guedeau-Boudeville +7
We report on the uptake, toxicity and degradation of magnetic nanowires by NIH/3T3 mouse fibroblasts. Magnetic nanowires of diameters 200 nm and lengths comprised between 1 μm and…
Adsorption of hydrophobic polyelectrolytes as studied by \emph{in situ} high energy X-Ray reflectivity
Damien Baigl, Marie-Alice Guedeau-Boudeville, Raymond Ober +5
A series of well-defined hydrophilic and hydrophobic polyelectrolytes of various chain lengths and effective charge fractions have been adsorbed onto oppositely charg…
Coiling Instability of Multilamellar Membrane Tubes with Anchored Polymers
Ilan Tsafrir, Marie-Alice Guedeau-Boudeville, Daniel Kandel +1
We study experimentally a coiling instability of cylindrical multilamellar stacks of phospholipid membranes, induced by polymers with hydrophobic anchors grafted along their hydrop…
Pearling Instabilities of Membrane Tubes with Anchored Polymers
Ilan Tsafrir, Dror Sagi, Tamar Arzi +4
We have studied the pearling instability induced on hollow tubular lipid vesicles by hydrophilic polymers with hydrophobic side groups along the backbone. The results show that the…
Coiling of Cylindrical Membrane Stacks with Anchored Polymers
Vidar Frette, Ilan Tsafrir, Marie-Alice Guedeau-Boudeville +3
We study experimentally a coiling instability of cylindrical multilamellar stacks of phospholipid membranes, induced by polymers with hydrophobic anchors grafted along their hydrop…
