Rotational microrheology of Maxwell fluids using micron-sized wires
Rémy Colin, Loudjy Chevry, Jean-François Berret +1
We demonstrate a simple method for rotational microrheology in complex fluids, using micrometric wires. The three-dimensional rotational Brownian motion of the wires suspended in M…
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…
Sub-Piconewton Force Detection using Micron-Size Wire Deflections
L. Chevry, J. -F. Berret
The mechanical properties of nanostructured wires obtained by co-assembly of iron oxide particles are studied. The intrinsic magnetic properties of the wires are used to induce and…
Intracellular micro-rheology probed by micron-sized wires
L. Chevry, R. Colin, B. Abou +1
In the last decade, rapid advances have been made in the field of micro-rheology of cells and tissues. Given the complexity of living systems, there is a need for the development o…
Fabrication of magnetic clusters and rods using electrostatic co-assembly
M. Yan, L. Chevry, J. -F. Berret
Using a novel protocol for mixing oppositely charged colloids and macromolecules, magnetic clusters and rods are fabricated using 10 nm-iron oxide nanoparticles and polymers. Here,…
3D rotational diffusion microrheology using 2D video microscopy
Rémy Colin, Minhao Yan, Loudjy Chevry +2
We propose a simple way to perform three-dimensional (3D) rotational microrheology using two-dimensional (2D) video microscopy. The 3D rotational brownian motion of micrometric wir…
