Photoacoustic viscoelasticity imaging dedicated to mechanical characterization of biological tissues [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2017
Since changes in mechanical properties of biological tissues are often closely related to pathology, the viscoelastic properties are important physical parameters for medical diagnosis.

Membrane viscoelasticity

open access: yesBiophysical Journal, 1976
In this paper, we develop a theory for viscoelastic behavior of large membrane deformations and apply the analysis to the relaxation of projections produced by small micropipette aspiration of red cell discocytes. We show that this relaxation is dominated by the membrane viscosity and that the cytoplasmic and extracellular fluid flow have negligible ...

Prediction Formula Describing Viscoelasticity of Unvulcanized Rubber Compound Based on Time-Temperature Equivalent Superposition Principle

open access: yesInternational Journal of Polymer Science, 2023
Fitting unvulcanized rubber compound’s (URC) dynamic viscoelasticity prediction formula and then constructing its mechanical constitutive model are of great significance for studying defect mechanisms in rubber products.

Viscoelasticity, Like Forces, Plays a Role in Mechanotransduction

open access: yesFrontiers in Cell and Developmental Biology, 2022
Viscoelasticity and its alteration in time and space has turned out to act as a key element in fundamental biological processes in living systems, such as morphogenesis and motility.

Consolidation of Viscoelastic Soil With Vertical Drains for Continuous Drainage Boundary Conditions Incorporating a Fractional Derivative Model

open access: yesFrontiers in Materials, 2021
In geotechnical engineering, vertical drainage is the most economical method for accelerating the consolidation of a large area of soft ground. In this study, we analyze the viscoelasticity of the soil and the actual drainage conditions on the top ...

Linear viscoelasticity of entangled wormlike micelles bridged by telechelic polymers : an experimental model for a double transient network [PDF]

open access: yes, 2007
We survey the linear viscoelasticity of a new type of transient network: bridged wormlike micelles, whose structure has been characterized recently [Ramos and Ligoure, (2007)].

Magnetic microrheometry of tumor-relevant stiffness levels and probabilistic quantification of viscoelasticity differences inside 3D cell culture matrices.

open access: yesPLoS ONE, 2023
The progression of breast cancer involves cancer-cell invasions of extracellular matrices. To investigate the progression, 3D cell cultures are widely used along with different types of matrices.
