The Hitchhiker's Guide to Differential Dynamic Microscopy
Enrico Lattuada, Fabian Krautgasser, Maxime Lavaud +2
Over nearly two decades, Differential Dynamic Microscopy (DDM) has become a standard technique for extracting dynamic correlation functions from time-lapse microscopy data, with ap…
Anomalous relaxation of coarsening foams with viscoelastic continuous phase
Chiara Guidolin, Emmanuelle Rio, Roberto Cerbino +2
We investigate the ultraslow structural relaxation of ageing foams with rheologically-tunable continuous phases. We probe the bubble dynamics associated with pressure-driven foam c…
Matrix viscoelasticity decouples bubble growth and dynamics in coarsening foams
Chiara Guidolin, Emmanuelle Rio, Roberto Cerbino +2
Pressure-driven coarsening triggers bubble rearrangements in liquid foams. Our experiments show that changing the continuous phase rheology can alter these internal bubble dynamics…
Multiscale dynamics in yield stress fluids during homogeneous and shear-banded yielding
P. Edera, M. Brizioli, M. Madani +6
Whether homogeneous and shear-banded yielding involve distinct microscopic mechanisms remains unresolved. We combine oscillatory rheology with gradient-resolved particle tracking t…
Protein sizing with Differential Dynamic Microscopy
Chiara Guidolin, Christopher Heim, Nathan B P Adams +4
Introduced more than fifty years ago, dynamic light scattering is routinely used to determine the size distribution of colloidal suspensions, as well as of macromolecules in soluti…
Non-invasive measurement of nuclear relative stiffness from quantitative analysis of microscopy data
Stefano Villa, Andrea Palamidessi, Emanuela Frittoli +3
The connection between the properties of cell tissue and those of the single constituent cells remains to be elucidated. At the purely mechanical level, the degree of rigidity of d…
Deformation profiles and microscopic dynamics of complex fluids during oscillatory shear experiments
Paolo Edera, Matteo Brizioli, Giuliano Zanchetta +3
Oscillatory shear tests are widely used in rheology to characterize the linear and non-linear mechanical response of complex fluids, including the yielding transition. There is an…
Differential dynamic microscopy for the characterization of polymer systems
Roberto Cerbino, Fabio Giavazzi, Matthew E. Helgeson
This review summarizes recent progress in investigating polymer systems by using Differential dynamic microscopy (DDM), a rapidly emerging approach that transforms a commercial mic…
Probing roto-translational diffusion of small anisotropic colloidal particles with a bright-field microscope
Fabio Giavazzi, Antara Pal, Roberto Cerbino
Soft and biological materials are often composed of elementary constituents exhibiting an incessant roto-translational motion at the microscopic scale. Tracking this motion with a…
Optimal leap angle of legged and legless insects in a landscape of uniformly-distributed random obstacles
Fabio Giavazzi, Samuele Spini, Marina Carpineti +1
We investigate theoretically the ballistic motion of small legged insects and legless larvae after a jump. Notwithstanding their completely different morphologies and jumping strat…
Multiple dynamic regimes in a coarsening foam
Fabio Giavazzi, Veronique Trappe, Roberto Cerbino
We use differential dynamic microscopy and particle tracking to determine the dynamical characteristics of a coarsening foam in reciprocal and direct space. At all wavevectors …
Dark Field Differential Dynamic Microscopy enables the accurate characterization of the roto-translational dynamics of bacteria and colloidal clusters
Roberto Cerbino, Davide Piotti, Marco Buscaglia +1
Micro- and nanoscale objects with anisotropic shape are key components of a variety of biological systems and inert complex materials, and represent fundamental building blocks of…
Differential Dynamic Microscopy microrheology of soft materials: a tracking-free determination of the frequency-dependent loss and storage moduli
Paolo Edera, Davide Bergamini, Véronique Trappe +2
Particle tracking microrheology (PT-r) exploits the thermal motion of embedded particles to probe the local mechanical properties of soft materials. Despite its appealing concep…
Correcting artifacts from finite image size in Differential Dynamic Microscopy
Fabio Giavazzi, Paolo Edera, Peter J. Lu +1
Differential Dynamic Microscopy (DDM) analyzes traditional real-space microscope images to extract information on sample dynamics in a way akin to light scattering, by decomposing…
Giant fluctuations and structural effects in a flocking epithelium
Fabio Giavazzi, Chiara Malinverno, Salvatore Corallino +3
Epithelial cells cultured in a monolayer are very motile in isolation but reach a near-jammed state when mitotic division increases their number above a critical threshold. We have…
Flocking Transition in Confluent Tissues
Fabio Giavazzi, Matteo Paoluzzi, Marta Macchi +5
Collective cell migration underlies important biological processes, such as embryonic development, wound healing and cancer invasion. While many aspects of single cell movements ar…
Equilibrium and non-equilibrium concentration fluctuations in a critical binary mixture
Fabio Giavazzi, Alessandro Fornasieri, Alberto Vailati +1
When a macroscopic concentration gradient is present across a binary mixture, long-ranged non-equilibrium concentration fluctuations (NCF) appear as a consequence of the coupling b…
Geometry for a `penguin-albatross' rookery
Fabio Giavazzi, Alberto Vailati
We introduce a simple ecological model describing the spatial organization of two interacting populations whose individuals are indifferent to conspecifics and avoid the proximity…
