Summary
This review introduces "liquid surface chemistry" to functionalize emulsion interfaces, crucial for applications in food, cosmetics, and healthcare. It categorizes methods like drop-coating and emulsifier-carriers for advanced material design.
Area of Science:
- Colloid and Surface Chemistry
- Materials Science
- Nanotechnology
Background:
- Emulsions are vital in food, cosmetics, healthcare, and materials science.
- Functionalizing emulsion interfaces is key for targeted applications but challenging due to drop fragility.
- Existing methods lack a unified framework for liquid surface modification.
Purpose of the Study:
- To present a unified framework for emulsion interface functionalization through "liquid surface chemistry."
- To categorize and analyze existing functionalization techniques.
- To identify future directions for enhanced control and versatility.
Main Methods:
- Categorization of methods into drop-coating strategies (layer-by-layer, polymer coating, polydopamine) and emulsifier-carrier approaches (particles, amphiphilic molecules).
- Transversal discussion of physico-chemical principles underlying these methods.
- Comparative analysis of advantages, limitations, and potential improvements.
Main Results:
- Established a classification of emulsion interface functionalization techniques.
- Highlighted the principles, benefits, and drawbacks of various methods.
- Identified polydopamine as a key polymer coating strategy.
Conclusions:
- Liquid surface chemistry offers a promising approach to engineer emulsion interfaces.
- Future directions include DNA-based programmability and AI for greater versatility and control.
- This framework advances the design of functional emulsions for diverse applications.

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

Solution, Solubility, and Solubility Equilibrium
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules,...

12.5K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

01:20Factors Affecting Dissolution: Drug Permeability, Stability and Stereochemistry
178
Orally administered drugs primarily enter the systemic circulation via passive diffusion through the intestinal membranes. The drug's absorption is influenced by drug stability in the gastrointestinal GI tract, membrane permeability, the surface area available for absorption, luminal drug concentration, and residence time in the lumen. Drug permeability can be enhanced by adjusting the lipophilicity, polarity, or molecular size of the drug, promoting its passive transport across intestinal...

01:25Esters to Carboxylic Acids: Saponification
4.4K
Esters can be hydrolyzed to carboxylic acids under acidic or basic conditions. Base-promoted hydrolysis of esters is a nucleophilic acyl substitution reaction in which esters react with an aqueous base, followed by an acid to give carboxylic acids. This reaction is also known as saponification because it forms the basis for making soaps from fats.
The reaction requires a base in stoichiometric amounts, which participates in the reaction and is not regenerated later. So, the base acts as a...

01:23Factors Affecting Dissolution: Particle Size and Effective Surface Area
731
Dissolution kinetics, an essential aspect of oral drug delivery, is significantly influenced by the drug's particle size. According to the Noyes-Whitney dissolution model, the dissolution rate correlates directly with the drug's surface area. The larger the surface area, the higher the drug's solubility in water, leading to a faster drug dissolution rate. Reducing particle size increases the effective surface area, enhancing the dissolution process. Micronization and nanosizing are...
