Integrating ultrafast and stochastic dynamics studies of Brownian motion in molecular systems and colloidal particles
Publication date: Available online 14 November 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Guilherme H. Oliveira, Rene A. NomeAbstractUltrafast spectroscopy and stochastic dynamics studies of chemical dynamics in solution with high resolution in both space and time have been undertaken for many years, but it is still challenging to connect fundamental knowledge obtained from stroboscopic approaches at ultrashort timescales and small length scales with that obtained by directly measuring individual particle motion at longer timescales. Therefore, it is interesting, conceptually and experimentally, t...

Enzyme encapsulation in nanostructured self-assembled structures: Toward biofunctional supramolecular assemblies
Publication date: December 2019Source: Current Opinion in Colloid & Interface Science, Volume 44Author(s): Maria Valldeperas, Andrea Salis, Justas Barauskas, Fredrik Tiberg, Thomas Arnebrant, Valdemaras Razumas, Maura Monduzzi, Tommy NylanderAbstractEnzymes have come into use for many new applications outside their natural biological environment, taking advantage of their high efficiency and selectivity as biocatalysts. Such new application often requires encapsulation to preserve the structure and activity of the enzyme, but also to regulate and control the activity. Here, we will discuss two types of encapsulation, soft ...

Ion-Micelle Interactions and the Modeling of Reactivity in Micellar Solutions of Simple Zwitterionic Sulfobetaine Surfactants
Publication date: Available online 9 November 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Gustavo T.M. Silva, Frank H. QuinaAbstractAqueous micellar solutions of sulfobetaine surfactants provide a simple physical-chemical system for investigating the origin and consequences of the specific interactions of anions with a model zwitterionic interface. Studies of ground-state reaction kinetics in micellar solutions of these surfactants provide a window into some of the more intriguing aspects of both anion and cation interactions with a zwitterionic micelle surface. Recent molecular dynamics simulation...

Boundary layers and surface forces in pure nonaqueous liquids
Publication date: December 2019Source: Current Opinion in Colloid & Interface Science, Volume 44Author(s): Ludmila B. BoinovichAbstractFurther progress has taken place in the experimental studies and molecular simulations of the structure and properties of boundary layers and thin interlayers of pure nonaqueous liquids. Recent findings in the field, including a deviation of density and shear response, layering static and dynamic structuring upon interlayer thinning are discussed in the context of the surface forces and the disjoining pressure contribution to the liquid film stability.

Progress in NMR studies of surfactant systems
Publication date: Available online 6 November 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Xingcen Liu, Qun Yu, Aixin Song, Shuli Dong, Jingcheng HaoABSTRACTNuclear magnetic resonance (NMR), as a powerful technology, is widely used to characterize the physicochemical properties of surfactants in solution. As a sensitive technique to molecular environment, NMR is beyond the reach of other spectral methods in surfactant systems. Recent years, intensive investigations of surfactants with NMR were reported but not well summarized, therefore we highlight these significant progresses, which may shed light...

Electrical double layers as ion reservoirs: applications to the deionization of solutions
Publication date: December 2019Source: Current Opinion in Colloid & Interface Science, Volume 44Author(s): A.V. Delgado, M.L. Jiménez, G.R. Iglesias, S. AhualliAbstractIn this work, we briefly review the basics of the structure of the electrical double layer (EDL), with emphasis on the amount of neutral salt that can be accumulated in the EDLs of opposite electrodes when a potential difference is applied. A realistic description of the solution is considered by taking into account that ions have finite volumes and have a limited concentration at any point, as well as the effect of ion charge. As a result of this accumulat...

On the analysis of ionic surface conduction to unravel charging processes at macroscopic soft and hard solid-liquid interfaces
Publication date: Available online 28 October 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Ralf Zimmermann, Jérôme F.L. Duval, Carsten WernerAbstractThe electrohydrodynamics of soft interfaces and the processes underlying interfacial charge formation by e.g. unsymmetrical ion adsorption are important aspects of current research on electrosurface phenomena. In particular, the recent progress in both fields greatly benefits from the now-possible accurate evaluation and quantitative interpretation of (ionic) excess conductivities at solid surfaces and in 3D polyelectrolytic architectures, respectivel...

Control of surface forces through hydrated boundary layers
Publication date: Available online 18 October 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Weifeng Lin, Jacob KleinAbstractHydration layers surrounding charges or zwitterionic moieties have long been known to play important roles in areas including antifouling and colloidal stability, and, particularly over the past 15 years or so, their role in boundary lubrication has been widely investigated. Hydration repulsion due to hydrated ions or polar groups present on surfaces may dominate their interactions at high electrolyte concentrations, so that Derjaguin-Landau-Verwey-Overbeek (DLVO) theory doesn�...

Capsules from Pickering emulsion templates
Publication date: Available online 15 October 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Ana Maria Bago Rodriguez, Bernard P. BinksAbstractFollowing the resurgence of interest in particle-stabilised or Pickering emulsions recently, the preparation of capsules from such templates has become feasible. We review some of the recent activity in this area and focus on both the methods used to reinforce the particle shell and the applications of these novel capsules, which may be empty or liquid-filled. The methods reported include interfacial polymerisation or crystallisation, interfacial cross-linking,...

Interplay between amphiphilic peptides and nanoparticles for selective membrane destabilization and antimicrobial effects
Publication date: Available online 14 October 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Sara Malekkhaiat Häffner, Martin MalmstenAbstractAs a result of an increasing number of bacteria developing resistance against antibiotics, antimicrobial peptides (AMPs) are attracting significant interest, particularly in relation to identification of peptides displaying potent but selective effects. Much less focus has been placed on delivery systems for AMPs, despite AMPs suffering from delivery challenges related to their size, cationicity, and amphiphilicity. Inorganic nanoparticles may provide opportuni...
