Scaling Perspectives of Underscreening in Concentrated Electrolyte Solutions
Samuel Safran, Philip Pincus
We present a scaling view of underscreening observed in salt solutions in the range of concentrations greater than about 1M, in which the screening length increases with concentrat…
Mesoscale phase separation of chromatin in the nucleus
Gaurav Bajpai, Daria Amiad-Pavlov, Dana Lorber +2
Intact-organism imaging of Drosophila larvae reveals and quantifies chromatin-aqueous phase separation. The chromatin can be organized near the lamina layer of the nuclear envelope…
Affinity and valence impact the extent and symmetry of phase separation of multivalent proteins
Saroj Kumar Nandi, Daniel Österle, Meta Heidenreich +2
Biomolecular self-assembly spatially segregates proteins with a limited number of binding sites (valence) into condensates that coexist with a dilute phase. We develop a many-body…
Screening length for finite-size ions in concentrated electrolytes
Ram M. Adar, Samuel A. Safran, Haim Diamant +1
The classical Debye-Huckel (DH) theory clearly accounts for the origin of screening in electrolyte solutions and works rather well for dilute electrolyte solutions. While the Debye…
Scaling laws for the response of nonlinear elastic media with implications for cell mechanics
Yair Shokef, Samuel A. Safran
We show how strain stiffening affects the elastic response to internal forces, caused either by material defects and inhomogeneities or by active forces that molecular motors gener…
Nematic order by elastic interactions and cellular rigidity sensing
Benjamin M. Friedrich, Samuel A. Safran
We predict spontaneous nematic order in an ensemble of active force generators with elastic interactions as a minimal model for early nematic alignment of short stress fibers in no…
