The pair potential of colloidal stars
F. Huang, K. Addas, A. Ward +5
We report on the construction of colloidal stars: 1 micrometer polystyrene beads grafted with a dense brush of 1 micrometer long and 10 nm wide semi-flexible filamentous viruses. T…
Entropy driven formation of a chiral liquid crystalline phase of helical filaments
Edward Barry, Zach Hensel, Michael Shribak +2
We study the liquid crystalline phase behavior of a concentrated suspension of helical flagella isolated from {\it Salmonella typhimurium}. Flagella are prepared with different pol…
Self-diffusion of rod-like viruses in the nematic phase
M. Paul Lettinga, Edward Barry, Zvonimir Dogic
We measure the self-diffusion of colloidal rod-like virus {\it fd} in an isotropic and nematic phase. A low volume fraction of viruses are labelled with a fluorescent dye and disso…
Flow behavior of colloidal rod-like viruses in the nematic phase
M. Paul Lettinga, Zvonimir Dogic, Hao Wang +1
The behavior of a colloidal suspension of rod-like {\it fd} viruses in the nematic phase, subjected to steady state and transient shear flows is studied. The monodisperse nature of…
Isotropic-nematic phase transition in suspensions of filamentous virus and the neutral polymer Dextran
Zvonimir Dogic, Kirstin Purdy, Eric Grelet +2
We present an experimental study of the isotropic-nematic phase transition in an aqueous mixture of charged semi-flexible rods (fd virus) and neutral polymer (Dextran). A complete…
Elongation and fluctuations of semi-flexible polymers in a nematic solvent
Z. Dogic, J. Zhang, A. W. C. Lau +7
We directly visualize single polymers with persistence lengths ranging from to 16 m, dissolved in the nematic phase of rod-like {\it fd} virus. Polymers with suffi…
