TLDR
Active, probe-based microrheological techniques for measuring the flow and deformation of complex fluids are introduced and recent results are reviewed, paying particular attention to comparing and contrasting rheological parameters obtained from micro- and macro-rheological Techniques.Abstract:
We introduce active, probe-based microrheological techniques for measuring the flow and deformation of complex fluids. These techniques are ideal for mechanical characterization either when little sample is available, or when samples show significant spatial heterogeneity. We review recent results, paying particular attention to comparing and contrasting rheological parameters obtained from micro- and macro-rheological techniques.read more

Recent advances in anisotropic magnetic colloids: realization, assembly and applications
TL;DR: This perspective article will give an overview of recent experimental results related to the realization and use of anisotropic magnetic colloids, i.e. microscopic particles having the shape, composition or structured surface which set a preferred magnetization direction.
Journal ArticleDOI
Microrheology of colloidal systems
TL;DR: T theoretical models available in the literature for both passive and active microrheology are discussed, focusing on the case of single-probe motion in model colloidal host media and some unexpected features, such as superdiffusive motion of the probe related to the breaking of nearest-neighbor cages.
Forced Motion of a Probed Particule Near the Colloidal Glass Transition
TL;DR: In this article, the authors used confocal microscopy to study the motion of a magnetic bead in a dense colloidal suspension, near the colloidal glass transition volume fraction g. The relationship between force and velocity becomes increasingly nonlinear as g is approached.

Forces of a single-beam gradient laser trap on a dielectric sphere in the ray optics regime.
TL;DR: It is shown that good trapping requires high convergence beams from a high numerical aperture objective and a comparison is given of traps made using bright field or differential interference contrast optics and phase contrast optics.
