vitamins, antioxidants, enzymes, vaccines, hormones), which are be then slowly released. Patchy clusters were doped with rhodamine B and distribution of dye molecules in the structure was analyzed with a laser scanning confocal microscope as shown in Figure 3. Aqueous Two-Phase Droplet-Templated Colloidosomes Composed of Self-Formed Particles via Spatial Confined Biomineralization. for pharmaceutical and cosmetic products. Furthermore, in this study, structure can be fixed by UV irradiation in a few seconds because the emulsion drop is photocurable and stabilized with adsorbed particles without any consolidating additives. 17 publications. Finally Surface Evolver simulation was performed to predict the structures of patchy clusters and the surface energy reduction by the particle adsorption as a function of the emulsion drop volume. The size of the parches depends on the volume of the emulsion drop and the surface properties such as the contact angle. Pickering emulsions are stabilized by solid particles.

However, if solid particles are added to the mixture, they will bind to the surface of the interface and prevent the droplets from coalescing, thus causing the emulsion to be more stable. In particular, when the particles are bound to the interface strongly, only tangential movement is allowed with a constant contact angle which determines the position of the contact line. Ultrasonic Dispersion of Fumed Silica: The Hielscher ultrasonic homogenizer UP400S disperses silica powder fast and efficiently into single nano particles. An example of a Pickering emulsion is oil droplets dispersed in water and armored with a layer of inorganic particles at their surface. Colloids protruding from a droplet surface can simultaneously adsorb to another interface, bridging two droplets. You’ve supercharged your research process with ACS and Mendeley! They use UV-curable oil as the emulsion phase and an aqueous colloidal suspension as the continuous phase. This page was last modified on 30 November 2011, at 14:21. Remarkably, stable emulsions are obtained from the all-biocompatible materials that can be broken either via dilution or surfactant addition. Whilst bare as well as functionalized silica (SiO2) is one of the most commonly used particle, other particles such as Fe3O4, hydroxyapatite, monodisperse polystyrene latex particles, cyclodextrine and maltodextrine, halloysite nanotubes, hematite (α-Fe2O3) microparticles, poly(methyl methacrylate) (PMMA), insoluble chitosan/gelatin-B complex particles etc. For permission to reproduce, republish and http://pubs.acs.org/page/copyright/permissions.html. In particle-stabilized Pickering emulsions or bubbles, the colloidal particles are adsorbed on the liquid-liquid or liquid-gas interface to reduce the surface energy.
