  journal={Soft Matter},
We report a simple route to form robust, inorganic, semi-permeable compartments composed of montmorillonite, a natural plate-like clay mineral that occurs widely in the environment. Mechanical forces due to shear in a narrow gap assemble clay nanoplates from an aqueous suspension onto air bubbles. Translucent vesicles suspended in a single-phase liquid are produced when the clay-covered air bubbles are exposed to a variety of water-miscible organic liquids and water-soluble surfactants. These…

Unmodified Clay Nanosheets at the Air–Water Interface
This work shows that clay nanosheets without any modification can be located at air–deionized-water interfaces, and finds that clay sheets modified by a branched polymer are much more likely to be confined to the interface.
Fabrication of fibrillosomes from droplets stabilized by protein nanofibrils at all-aqueous interfaces
Protein nanofibrils are used to generate colloidosome-like two-dimensional crosslinked networks of nanostructures templated by all-aqueous emulsions, which are term fibrillosomes and open up the possibility of stabilizing aqueous two-phase systems using natural proteins, and creating self-standing protein capsules without the requirement for three-phase emulsion or water/oil interfaces.
Cellulose Abetted Assembly and Temporally Decoupled Loading of Cargo into Vesicles Synthesized from Functionally Diverse Lamellar Phase Forming Amphiphiles.
It is shown that cellulose, in the form of cellulose paper, facilitates the assembly of membranous vesicles 5-20 μm in diameter from scientifically and technologically important amphiphiles of diverse chemical structures and functionality such as fatty acids (fatty acid vesicle), amphiphilic diblock copolymers, and Amphiphilic triblockCopolymers (polymersomes).
Nano-mechanical properties of clay-armoured emulsion droplets
There has been a growing interest in understanding the stabilization mechanism of particle-armoured emulsion droplets over the last few decades due to their importance in many everyday products.
Nanoparticle-based membrane assembly and silicification in coacervate microdroplets as a route to complex colloidosomes.
The integration of colloidosome and coacervate technologies offers a route to a new type of multifunctional microcompartmentalized system based on the membrane-mediated incarceration of molecularly crowded chemical environments.
Electrostatically gated membrane permeability in inorganic protocells.
This work uses crosslinking and covalent grafting of a pH-responsive copolymer to generate an ultrathin elastic membrane that exhibits selective release and uptake of small molecules within the protocell aqueous interior.

Clays are the siblings of graphite and graphene/graphene-oxide. There are two basic ways of using clays for encapsulation of sub-micron entities such as molecules, droplets, or nanoparticles, which
Small-molecule uptake in membrane-free peptide/nucleotide protocells
The results suggest that understanding the mechanisms of molecular uptake into coacervate droplets could provide an important step towards the rational design of molecularly crowded microscale dispersions that display complex fluid behavior, compartment-mediated functionality and primitive aspects of synthetic cellularity.
Chemical Signaling and Functional Activation in Colloidosome-Based Protocells.
The emergence of new functionalities in inorganic colloidosomes via chemical communication between different protocell populations provides a first step toward the realization of interacting communities of synthetic functional microcompartments.


Liposomes from ionic, single-chain amphiphiles.
Membrane permeability to various solutes was determined in part by a new technique which utilized phase-contract microscopy; when impermeable vesciles exclude added solutes such as sucrose, refractive index differences are created between vesicle contents and surrounding medium, so that the vesicles appear bright in the phase microscope.
Colloidosomes: Selectively Permeable Capsules Composed of Colloidal Particles
An approach to fabricate solid capsules with precise control of size, permeability, mechanical strength, and compatibility is presented, which are hollow, elastic shells whose permeability and elasticity can be precisely controlled.
Partitioning of clay colloids at air-water interfaces.
The results show the importance of electrostatic interactions between the air-water interface and colloids, especially the influence of pH-dependent edge charges, and influence of particle shape.
Aggregation of montmorillonite and organic matter in aqueous media containing artificial seawater
It is postulated that the composition of suspended particles, specifically the availability of steric polymers such as those contained in humic acid, determine whether the river suspension is rapidly aggregated and settled or remains dispersed in suspension when it encounters increasingly saline environments of estuaries and oceans.
The effect of double-chain surfactants on armored bubbles: a surfactant-controlled route to colloidosomes.
The method is a simple one-step process for obtaining colloidosomes from particle-covered bubbles and finds that the gas phases of air bubbles covered with anionic or cationic polystyrene latex particles dissolve on exposure to cationsic and catanionic surfactants.
Assembly of Latex Particles by Using Emulsion Droplets as Templates. 1. Microstructured Hollow Spheres
We describe an emulsion-based technique that allows the assembly of colloid particles into microstructured or multicomponent clusters (“supraparticles”). The particles are gathered, assembled, and
Tubular precipitation and redox gradients on a bubbling template.
This work reports a self-organized periodic templating mechanism producing tubular structures electrochemically in iron-ammonium-sulfate solutions; iron oxides precipitate on the surface of bubbles that linger at the tube rim and then detach, leaving behind a ring of material.
Synthesis of long prebiotic oligomers on mineral surfaces
This work describes a system that models prebiotic polymerization by the oligomerization of activated monomers—both nucleotides and amino acids, and finds that whereas the reactions in solution produce only short oligomers, the presence of mineral surfaces induces the formation of oligomers up to 55 monomers long.
pH-Triggered softening of crosslinked hydrogen-bonded capsules.
The first AFM single capsule mechanical measurements on hydrogen-bonded polymeric multilayer microcapsules made of poly(vinylpyrrolidone)/poly(methacrylic acid) (PVPON/PMAA), as well as of capsules derived from these systems chemical crosslinking, found elastic modulus of 610 MPa for low pH (= 2) is typical for a highly stable, glass-like structure similar to electrostatically bound multilayers.
