The isotropic-cholesteric phase transition of filamentous virus suspensions as a function of rod length and charge
Kirstin Purdy, Seth Fraden
The viruses studied are genetically engineered, charged, semiflexible filamentous bacteriophages that are structurally identical to M13 virus, but differ either in contour length o…
The influence of charge and flexibility on smectic phase formation in filamentous virus suspensions
Kirstin Purdy, Seth Fraden
We present experimental measurements of the cholesteric-smectic phase transition of suspensions of charged semiflexible rods as a function of rod flexibility and surface charge. Th…
Nematic phase transitions in mixtures of thin and thick colloidal rods
Kirstin Purdy, Szabolcs Varga, Amparo Galindo +2
We present the first experimental measurements of the isotropic and nematic phases of mixtures of thin, charged semiflexible fd virus, and thick, fd-PEG created by covalently graft…
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…
Measuring the nematic order of colloidal fd virus by xray diffraction
K. R. Purdy, Z. Dogic, S. Fraden +3
The orientational distribution function of the nematic phase of the semi-flexible rod-like virus fd is measured by x-ray diffraction as a function of concentration and ionic streng…
