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 applications of Pickering emulsions have attracted attention due to the benefit of the rapid development of particle synthesis techniques and the discovery of new colloids with adjustable surface properties, in addition to their constancy, their high payload capacity, and most importantly, the. Although most of the investigation on Pickering emulsions has been based on model systems with inorganic or organic solid particles, recent advances have been made regarding the application of nanocarriers, protein-based. Consequently, the exploration of Pickering emulsions for biphasic catalysis is a hot topic in the study of applications of 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. Biomedical Applications of Pickering Emulsions. Areas covered: Particle-stabilized emulsions, also known as Pickering emulsions, have garnered interest in recent years. Pickering emulsions are an ideal platform for biphasic catalysis because of their enhanced stability, large interfacial area, facile product separation, and easy catalyst recycling.

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.
