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…
Pore Stability and Dynamics in Polymer Membranes
Harry Bermudez, Helim Aranda-Espinoza, Daniel A. Hammer +2
Vesicles self-assembled from amphiphilic diblock copolymers exhibit a wide diversity of behavior upon electroporation, due to competitions between edge, surface and bending energie…
Electromechanical Limits of Polymersomes
H. Aranda-Espinoza, H. Bermudez, F. S. Bates +1
Self-assembled membranes of amphiphilic diblock copolymers enable comparisons of cohesiveness with lipid membranes over the range of hydrophobic thicknesses d=3-15 nm. At zero mech…
Electrostatically induced undulations of lamellar DNA-lipid complexes
H. Schiessel, H. Aranda-Espinoza
We consider DNA-cationic lipid complexes that form lamellar stacks of lipid bilayers with parallel DNA strands intercalated in between. We calculate the electrostatically induced e…
Electrostatic Repulsion of Positively Charged Vesicles and Negatively Charged Objects
Helim Aranda-Espinoza, Yi Chen, Nily Dan +4
A positively charged, mixed bilayer vesicle in the presence of negatively charged surfaces (for example, colloidal particles) can spontaneously partition into an adhesion zone of d…
