This review summarizes recent progress in investigating polymer systems by using Differential dynamic microscopy (DDM), a rapidly emerging approach that transforms a commercial microscope by combining real-space information with the powerful capabilities of conventional light scattering analysis. DDM analysis of a single microscope movie gives access to the sample dynamics in a wide range of scattering wave-vectors, enabling contemporary polymer science experiments that would be difficult or…

Optical-Tweezers-integrating-Differential-Dynamic-Microscopy maps the spatiotemporal propagation of nonlinear strains in polymer blends and composites

How local stresses propagate through polymeric fluids, and, more generally, how macromolecular dynamics give rise to viscoelasticity are open questions vital to wide-ranging scientific and industrial…

Deformation profiles and microscopic dynamics of complex fluids during oscillatory shear experiments.

The tracking free approach to oscillatory shear tests is intrinsically multi-scale, can successfully discriminate between different types of dynamics, and can be automated to minimize user intervention.

Fluorescence correlation spectroscopy in polymer science

Fluorescence correlation spectroscopy (FCS) is a well-established technique for studying dynamic processes and interactions with minimal invasion into the corresponding system. Even though FCS has…

Perspective: Differential dynamic microscopy extracts multi-scale activity in complex fluids and biological systems.

Differential dynamic microscopy can become a standard primary tool in every laboratory equipped with a microscope, at the very least as a first bias-free automated evaluation of the dynamics in a system.

Differential dynamic microscopy: probing wave vector dependent dynamics with a microscope.

The use of an ordinary white-light microscope for the study of the q-dependent dynamics of colloidal dispersions is demonstrated and the results are found to be in good agreement with the theoretically expected values for Brownian motion in a viscous medium.

Measuring capillary wave dynamics using differential dynamic microscopy.

This work demonstrates the first application of differential dynamic microscopy to the study of interfacial dynamics and finds capillary velocities on the order of 0.1 μm s-1 that depend on the sample composition in expected ways and that match values from the literature.

Scattering information obtained by optical microscopy: differential dynamic microscopy and beyond.

A theoretical model for microscope imaging is derived that accounts for the three-dimensional nature of the sample, the arbitrary coherence properties of the light source, and the effect of the finite numerical aperture of the microscope objective and extends to the class of microscopy techniques that can be described by a linear space-invariant imaging of the density of the scattering centers, which includes, for example, dynamic fluorescence microscopy.

Light-sheet microscopy with digital Fourier analysis measures transport properties over large field-of-view.

This combination, referred to as selective-plane illumination differential dynamic microscopy (SPIDDM), has the benefit of optical sectioning to study, with minimal photobleaching, thick samples allowing us to measure the diffusivity of colloidal particles at high volume fractions.

Characterizing concentrated, multiply scattering, and actively driven fluorescent systems with confocal differential dynamic microscopy.

ConDDM is introduced, a new technique yielding information comparable to that given by light scattering but in dense, opaque, fluorescent samples of micron-sized objects that cannot be probed easily with other existing techniques.
