Rheological Microscopy: Local Mechanical Properties from Microrheology

Physical Review Letters, 2003
We demonstrate how tracer microrheology methods can be extended to study submicron scale variations in the viscoelastic response of soft materials; in particular, a semidilute solution of lambda-DNA. The polymer concentration is depleted near the surfaces of the tracer particles, within a distance comparable to the polymer correlation length.

Mapping cellular-scale internal mechanics in 3D tissues with thermally responsive hydrogel probes

Nature Communications, 2020
Local mechanical properties are important to cellular function; but conventional measurement techniques are limited in intact, living, 3D tissues. Here, the authors report on swellable hydrogel microparticles to monitor mechanical properties in situ via ...

Local mechanical properties of white matter structures in the human brain [PDF]

NeuroImage, 2013
The noninvasive measurement of the mechanical properties of brain tissue using magnetic resonance elastography (MRE) has emerged as a promising method for investigating neurological disorders. To date, brain MRE investigations have been limited to reporting global mechanical properties, though quantification of the stiffness of specific structures in ...

Local nano-mechanical properties of cross-linked polybutylene [PDF]

, 2021
Cross-linking is a process in which polymer chains are associated through chemical bonds. The cross-linking level can be adjusted by the irradiation dosage and often by means of a cross-linking booster. The polymer additional cross-linking influences the
