Liposomes have been widely used as cellular and bioparticle mimics due to their lipid bilayer structure and relative ease of production and manipulation. Such biocolloids are frequently characterized by capillary electrophoresis (CE), which promises a wealth of information about such properties as surface charge, composition, and rigidity. The applicability of this information is somewhat limit...

Graphene exhibits a range of exceptional physical properties and holds great promise for development of novel bulk materials for widespread applications. Properly engineering of assembled structures of graphene at multiple length scales is essential to realize its full potential in bulk forms. In this Concept article, we highlight the unique colloidal and gelation behavior of a commonly used pr...

I t has generally been held in the colloidal literature that different anions of the same valency have different effects on such colloidal properties of proteins as swelling, viscosity, or osmotic pressure, and that the anions could be arranged in definite series according to their influence on these properties. Such series are known under the name of the Hofmeister series. A number of authors ...

Star polymers with tunable number and size of arms, and thus interactions, represent ideal model systems for exploring the regime of soft material behaviour that interpolates between hard spheres and polymeric coils. This regime is characterized by a rich variety of properties that reflect the combination of polymeric and colloidal features. In this review we discuss some of these properties, a...

dissolved nitrogen predispersed solvent extraction (dnpdse) is a new method devised for improving the performance of equipment utilized in the solvent extraction (sx) method, especially for dilute solutions. in this method, for mixing the two phases, bubble dispersion of the organic phase (colloidal gas aphrons [cgas]) is used instead of its drop dispersion in the aqueous phase. through increas...

Anisotropic colloidal particles constitute an important class of building blocks for self-assembly directed by electrical fields. The aggregation of these building blocks is driven by induced dipole moments, which arise from an interplay between dielectric effects and the electric double layer. For particles that are anisotropic in shape, charge distribution, and dielectric properties, calculat...

Synthetic colloidal spheres play a central role in applications as diverse as catalysis, medical diagnostics, and photonics. Even as many applications advance toward single-sphere implementations, methods for characterizing colloidal spheres typically offer only sampleaveraged overviews of such properties as spheres’ sizes and porosities. Moreover, such characterization methods as mercury adsor...

Colloidal magnetic nanoparticles are candidates for application in biology, medicine and nanomanufacturing. Understanding how these particles interact collectively in fluids, especially how they assemble and aggregate under external magnetic fields, is critical for high quality, safe, and reliable deployment of these particles. Here, by applying magnetic forces that vary strongly over the same ...
