Urea and salt induced modulation of protein interactions: implications for crystallization and liquid-liquid phase separation
Paper
One- and two-particle microrheology of soft materials based on optical-flow image analysis
We propose optical flow microrheology (OFM), a novel tracking-free approach to probe the rheology of soft materials.
Paper
Capturing the impact of protein unfolding on the dynamic assembly of protein networks
Protein force liability leads to dynamic change in building block shape, i.e. unfolding or changes in folded shape, resulting in a three-phase assembly process.

Tetratic phase in 2D crystals of squares
We report the tetratic phase as an intermediate phase between an isotropic fluid and a square crystal composed of micrometer sized squares in two dimensions. The squares are manufactured by direct laser writing in a photoresist.

Dynamical arrest for globular proteins with patchy attractions
Dynamic properties of γB-crystallin are incompatible with a colloid model for attractive ellipsoids that reproduces static data and phase diagrams.

Fine-tuning the architecture of microgels by varying the initiator addition time
We investigate the effect of varying the initiator addition time on the resulting structure of colloidal microgels.

Invitation to submit to ‘Colloidal interactions, dynamics and rheology’ collection in Soft Matter Physical Science of the Didodecyldimethylammonium Bromide – Water System: 1. Equilibrium Phase Behaviour
Using optical tweezer electrophoresis to investigate clay nanoplatelet adsorption on Latex microspheres in aqueous media
The adsorption kinetics of clay nanoplatelets on an optically trapped microsphere is driven by non-electrostatic dispersion and electrostatic interactions.

Crowding effects on the structure and rheology of ultrasoft PNIPAM–PEGMA copolymer microgels
The internal structure of PNIPAM–PEGMA copolymer microgels is linked to the single particle bulk modulus and the inter-particle interactions, determining the structural organization and rheology in dense states.

Spontaneous emergence of motion of an isotropic active particle in a Carreau fluid
Can isotropic active colloids self-propel in a Carreau fluid? The present study answers this question. Beyond a certain critical particle size, spontaneous motion is observed in such a fluid.
Paper
Quasi-two-dimensional dispersions of Brownian particles with competitive interactions: phase behavior and structural properties
Langevin dynamics simulations reveal that quasi-2D Brownian particles with competitive short-range attractive and long-range repulsive interactions exhibit hexagonal ordering and double-stranded cluster morphologies as temperature and density vary.

Pairing-specific microstructure in depletion gels of bidisperse colloids
We report the ensemble-averaged and pairing-specific network microstructure formed by short-range depletion attractions in bidisperse hard sphere-like colloidal systems.
Paper
Effective patchiness from critical points of a coarse-grained protein model with explicit shape and charge anisotropy
Critical points of an anisotropic, coarse-grained protein model are used to detemine an “effective patchiness” by comparison to the Kern–Frenkel patchy model.
Paper
Phase behavior of binary mixtures of hollow and regular microgels
Hollow microgels can suppress the formation of colloidal crystals at low size polydispersity due to their high deformability and capacity to buckle.
Cybloids – creation and control of cybernetic colloids
We present colloidal particles with freely selectable properties by external programming via a feedback loop. Here, the feedback potential depends on the past particle position(s) resulting in self-propulsion and self-organization into crystals.

We study the influence of core–shell morphology on the structural characteristics of nanogels.

About this collection
The issue aims to collect outstanding contributions in the areas of colloidal stability, dynamics under external fields, and the behaviour of complex colloidal dispersions. We welcome experimental, theoretical, and computational studies that advance our understanding of colloidal systems, highlighting topics such as phase behaviour, non-equilibrium dynamics, and the interplay between colloidal particles and their surrounding medium, as well as the development of advanced optical and mechanical tools to probe soft matter.
