However, even though many efforts have been done for the development of Pickering emulsion, some aspects still need further advancement. Finally, the importance of using Pickering emulsions to carry out reactions in flow and in multi-step cascade systems is highlighted with various examples to support the benefits of transferring this technology to industrial processes. The use of pickering emulsions is of high interest for applications. Finally, a large amount of applications of materials produced from Pickering emulsion systems, including both biomedical and other chemical or physical applications, are talked over. A section describing methods for recovering the catalyst is also included, in which various stimuli are discussed.
An overview is given regarding the kinds of liquid phases comprising the emulsion system, the different types of solid particle stabilizers (whether they contain catalyst or not) and the catalytic reactions studied. Pickering emulsion stabilization by hybrid nanoparticles (Tavasoli et al., 2022) and protein nanoparticles (Zhang et al., 2021) has been reviewed, as well as the potential of Pickering multiple emulsions (Klojdov and Stathopoulos, 2022) and high internal-phase Pickering emulsions (Abdullah et al., 2020) in food applications. As the area has advanced rapidly, the intention of this review is to summarize the latest innovations being reported. The emulsions have been used in several applications such as food, pharmaceutical, cosmetics and petroleum industries. Currently, there are two main categories of natural food grade particles used to prepare Pickering emulsions. They are first discovered by Ramsden (1) in 1903 that the mixture of wax and water. Certain Pickering emulsions remain stable even under gastric conditions. Application of Pickering emulsion in food. Pickering emulsions are stabilized by solid or soft nano (micro) particles. In the past 10 years a new application has emerged in the field of catalysis to use them as vehicles to carry out catalytic reactions, allowing a more environmentally friendly process with high conversions and selectivities and important advantages for catalyst recovery. Pickering emulsions find applications for enhanced oil recovery or water remediation. 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.
Particle-stabilised or Pickering emulsions are versatile systems. Biomedical Applications of Pickering Emulsions.
