Towards rational design of power-law rheology via DNA nanostar networks
Nathaniel Conrad, Omar A. Saleh, Deborah K. Fygenson
We measure the rheology of transient hydrogels comprised of a single type of DNA nanostar that makes both strong and weak bonds. These gels exhibit power-law frequency-dependence o…
Spatial Organization of Phase-separated DNA Droplets
Sam Wilken, Aria Chaderjian, Omar A. Saleh
Many recent studies of liquid-liquid phase separation in biology focus on phase separation as a dynamic control mechanism for cellular function, but it can also result in complex m…
Controlling liquid-liquid phase behavior with an active fluid
Alexandra M. Tayar, Fernando Caballero, Trevor Anderberg +3
Demixing of binary liquids is a ubiquitous transition, which is explained using a well-established thermodynamic formalism that requires equality of intensive thermodynamics parame…
Intrinsically Disordered Proteins at the Nano-scale
Tamara Ehm, Hila Shinar, Sagi Meir +6
The human proteome is enriched in proteins that do not fold into a stable 3D structure. These intrinsically disordered proteins (IDPs) spontaneously fluctuate between a large numbe…
Glassy dynamics and memory effects in an intrinsically disordered protein construct
Ian L. Morgan, Ram Avinery, Gil Rahamim +2
Glassy, nonexponential relaxations in globular proteins are typically attributed to conformational behaviors that are missing from intrinsically disordered proteins. Yet, we show t…
Single-molecule stretching shows glycosylation sets tension in the hyaluronan-aggrecan bottlebrush
Sarah N. Innes-Gold, John P. Berezney, Omar A. Saleh
Large bottlebrush complexes formed from the polysaccharide hyaluronan (HA) and the proteoglycan aggrecan contribute to cartilage compression resistance and are necessary for health…
Contraction of polymer gels created by the activity of molecular motors
Mattia Bacca, Omar A. Saleh, Robert M. McMeeking
We propose a theory based on non-equilibrium thermodynamics to describe the mechanical behavior of an active polymer gel created by the inclusion of molecular motors in its solvent…
