Solid friction between soft filaments
Andrew Ward,Feodor Hilitski,Walter Schwenger,David O. Welch,Andy W.C. Lau,Vincenzo Vitelli,Lakshminarayanan Mahadevan,Zvonimir Dogic +7 more
TL;DR: In this paper, the authors measured the sliding forces between two bundled F-actin filaments and showed that these frictional forces are unexpectedly large, scale logarithmically with sliding velocity as in solid-like friction, and exhibit complex dependence on the filaments' overlap length.
Solid friction between soft filaments

TL;DR: This work directly measuring the sliding forces between two bundled F-actin filaments shows that these frictional forces are unexpectedly large, scale logarithmically with sliding velocity as in solid-like friction, and exhibit complex dependence on the filaments' overlap length.

Measuring Cohesion between Macromolecular Filaments One Pair at a Time: Depletion-Induced Microtubule Bundling
Feodor Hilitski,Andrew Ward,Luis Cajamarca,Michael F. Hagan,Gregory M. Grason,Zvonimir Dogic +5 more
TL;DR: It is demonstrated that the minimal model of depletion, based on the Asakura-Oosawa theory, fails to quantitatively describe the experimental data, and pairwise additivity of depletion interactions for the specific experimental conditions is verified.
Microtubules soften due to cross-sectional flattening
Edvin Memet,Feodor Hilitski,Margaret A Morris,Walter Schwenger,Zvonimir Dogic,Zvonimir Dogic,Lakshminarayanan Mahadevan +6 more
TL;DR: The results demonstrate that properties of microtubules are highly dependent on the magnitude of the applied strain and offer a new interpretation for the large variety in microtubule mechanical data measured by different methods.
Static adhesion hysteresis in elastic structures
TL;DR: In this article, a minimal theory for the peeling of a thin sheet from a substrate, coupling the local event of bond breaking to the nonlocal elastic relaxation of the sheet and show that this can drive static adhesion hysteresis over a bonding/debonding cycle.
