Protein gradients in single cells induced by their coupling to "morphogen"-like diffusion
Saroj Kumar Nandi, Sam A. Safran
One of the many ways cells transmit information within their volume is through steady spatial gradients of different proteins. However, the mechanism through which proteins without…
Inter-filament Attractions Narrow the Length Distribution of Actin Filaments
David Biron, Elisha Moses, Itamar Borukhov +1
We show that the exponential length distribution that is typical of actin filaments under physiological conditions dramatically narrows in the presence of (i) crosslinker proteins…
Attractive instability of oppositely charged membranes induced by charge density fluctuations
Guy Hed, S. A. Safran
We predict the conditions under which two oppositely charged membranes show a dynamic, attractive instability. Two layers with unequal charges of opposite sign can repel or be stab…
Universal reduction of pressure between charged surfaces by long-wavelength surface charge modulation
D. B. Lukatsky, S. A. Safran
We predict theoretically that long-wavelength surface charge modulations universally reduce the pressure between the charged surfaces with counterions compared with the case of uni…
Elastic Interactions of Cells
U. S. Schwarz, S. A. Safran
Biological cells in soft materials can be modeled as anisotropic force contraction dipoles. The corresponding elastic interaction potentials are long-ranged ( with dist…
Phase behavior and material properties of hollow nanoparticles
U. S. Schwarz, S. A. Safran
Effective pair potentials for hollow nanoparticles like the ones made from carbon (fullerenes) or metal dichalcogenides (inorganic fullerenes) consist of a hard core repulsion and…
