Extracellular rigidity sensing by talin isoform-specific mechanical linkages. [PDF]

open access: yesNat Cell Biol, 2015
The ability of cells to adhere and sense differences in tissue stiffness is crucial for organ development and function. The central mechanisms by which adherent cells detect extracellular matrix compliance, however, are still unknown. Using two single-molecule-calibrated biosensors that allow the analysis of a previously inaccessible but ...

Mechanobiological Analysis of Nanoparticle Toxicity

open access: yesNanomaterials, 2023
Nanoparticles (NPs) are commonly used in healthcare and nanotherapy, but their toxicity at high concentrations is well-known. Recent research has shown that NPs can also cause toxicity at low concentrations, disrupting various cellular functions and ...

Variational inference of ice shelf rheology with physics-informed machine learning

open access: yesJournal of Glaciology, 2023
Floating ice shelves that fringe the coast of Antarctica resist the flow of grounded ice into the ocean. One of the key factors governing the amount of flow resistance an ice shelf provides is the rigidity (related to viscosity) of the ice that ...

α-Actinin links extracellular matrix rigidity-sensing contractile units with periodic cell-edge retractions. [PDF]

open access: yesMol Biol Cell, 2016
During spreading and migration, the leading edges of cells undergo periodic protrusion-retraction cycles. The functional purpose of these cycles is unclear.

Actin crosslinking by α-actinin averts viscous dissipation of myosin force transmission in stress fibers

open access: yesiScience, 2023
Summary: Contractile force generated in actomyosin stress fibers (SFs) is transmitted along SFs to the extracellular matrix (ECM), which contributes to cell migration and sensing of ECM rigidity.

Rigidity of frameworks supported on surfaces [PDF]

open access: yes, 2012
A theorem of Laman gives a combinatorial characterisation of the graphs that admit a realisation as a minimally rigid generic bar-joint framework in $\bR^2$.

Measurements of elastic moduli of silicone gel substrates with a microfluidic device. [PDF]

open access: yesPLoS ONE, 2011
Thin layers of gels with mechanical properties mimicking animal tissues are widely used to study the rigidity sensing of adherent animal cells and to measure forces applied by cells to their substrate with traction force microscopy.

Wearable Soft Microtube Sensors for Quantitative Home-Based Erectile Dysfunction Monitoring

open access: yesSensors, 2022
Quantifiable erectile dysfunction (ED) diagnosis involves the monitoring of rigidity and tumescence of the penile shaft during nocturnal penile tumescence (NPT). In this work, we introduce Erectile Dysfunction SENsor (EDSEN), a home-based wearable device
