Our first foray into ionic liquid-based Pickering emulsions was to simply replace the droplet phase in a conventional oil-in-water emulsion with an IL to create an IL-in-water Pickering emulsion. Deviating from the conventional oil-in-water emulsion systems, employing ILs allows for interesting interfacial phenomena due to the charged nature of the IL and other factors intrinsic to the liquid including ion ordering, interfacial tension, etc. Surfactant-free, solid-stabilized Pickering emulsions can act as templates for these studies in which the ionic liquid subsists as the droplet phase, continuous phase, or both phases in the emulsion. These suggest unique applications in extraction, catalysis, reaction schemes, etc., and provide even more extensive tunability through the complex interactions of differing choices of particles and ionic liquids. Additionally, by incorporating particles into these IL-liquid systems, novel and varied behaviors can be achieved. The extremely high tunability of the material properties of ionic liquids (ILs), caused by the virtually endless combinations of anions and cations, allows ILs to be unique candidates for the study of liquid-liquid interfaces. Unique morphologies of aqueous and nonaqueous ionic liquid Pickering emulsions There continues to be active research in Pickering emulsions, immiscible phases, and ILs, and one particularly relevant application is employing ionic liquid-in-water emulsions as “a new class of fluorescent sensors for metal ions”. Illustrates some of these phenomena-particle self-assembly on an emulsion surface, particle “bridging” between emulsion droplets, and spontaneous transport across the liquid-liquid interface-as well as an example of the molecular dynamics (MD) simulations used to further explore the fundamentals of IL interactions with other phases. It explores ionic liquid-liquid interfaces and their role in ionic liquid Pickering emulsions through both experimental and simulation approaches, including several unique and fascinating interface phenomena. This work focuses in particular on systems involving solid particles and immiscible liquid phases. Ionic liquids’ complex interactions with other materials enable multiphase systems that are both theoretically fascinating and potentially useful. doi: 10.1016/S1359-0294(02)00008-0.The unique properties and rich variety of ionic liquids (ILs) make them promising for a wide range of applications and the potential of pure ILs is multiplied by introducing them to multicomponent systems.

Mechanism and Application of Chitosan and Its Derivatives in Promoting Permeation in Transdermal Drug Delivery Systems: A Review. Pickering emulsion application solid particles. Through this review, we highlight the use of this type of emulsion and its excellent properties as permeability promoters of solid particles, providing ideal results for local drug delivery and use in Pickering emulsions. The objective of this review is to provide a theoretical basis for a broader type of emulsion, in addition to reviewing the main aspects related to the mechanisms and applications to promote its stability. In this review, the effects and characteristics of microparticles in the preparation and properties of Pickering emulsions are presented. The use of biodegradable and biocompatible stabilizers of natural origin, such as clay minerals, presents a promising future for the development of Pickering emulsions and, with this, they deliver some advantages, especially in the area of biomedicine. These solid particles of certain dimensions (micro- or nano-particles), and desired wettability, have been shown to be an alternative to conventional emulsifiers. Pickering emulsions are systems composed of two immiscible fluids stabilized by organic or inorganic solid particles.
