Molecular motors enhance microtubule lattice plasticity
William Lecompte, Karin John
Microtubules are key structural elements of living cells that are crucial for cell division, intracellular transport and motility. Recent experiments have shown that microtubule se…
Soft electrowetting
Ranabir Dey, Mathijs van Gorcum, Frieder Mugele +1
Electrowetting is a commonly used tool to manipulate sessile drops on hydrophobic surfaces. By applying an external voltage over a liquid and a dielectric-coated surface, one achie…
Actin based propulsion: Intriguing interplay between material properties and growth processes
Karin John, Denis Caillerie, Philippe Peyla +3
Eukaryotic cells and intracellular pathogens such as bacteria or viruses utilize the actin polymerization machinery to propel themselves forward. Thereby, the onset of motion and c…
Pearlnecklacelike chain conformation of hydrophobic polyelectrolyte: a SANS study of partially sulfonated polystyrene in water
François Boué, Marie Noelle Spiteri, Claudine Williams
The form factor of partially sulfonated polystyrene PSSNa (degree of sulfonation f =1, 0.72, 0.64 and 0.36), at polymer concentration 0.17M and 0.34M, without or with added salt (0…
Redispersible Hybrid Nanopowders: Cerium Oxide Nanoparticle Complexes with Phosphonated-PEG Oligomers
L. Qi, A. Sehgal, J. -C. Castaing +4
Rare earth cerium oxide (ceria) nanoparticles are stabilized using end-functional phosphonated-PEG oligomers. The complexation process and structure of the resulting hybrid core-sh…
Interactions between Polymers and Nanoparticles : Formation of Supermicellar Hybrid Aggregates
J. -F. Berret, K. Yokota, M. Morvan
When polyelectrolyte-neutral block copolymers are mixed in solutions to oppositely charged species (e.g. surfactant micelles, macromolecules, proteins etc), there is the formation…
