Summary
Novel surfactant vesicles spontaneously formed using a rough glass surface. These stable vesicles are robust against storage, heat, and freeze-thaw cycles, offering potential applications in various fields.
Area of Science:
- Materials Science
- Colloid and Surface Chemistry
Background:
- Surfactant self-assembly into vesicular structures is crucial for applications in drug delivery and nanotechnology.
- Controlling vesicle formation and stability often requires specific additives or complex procedures.
Purpose of the Study:
- To investigate the spontaneous formation of single-tailed surfactant (STS) vesicles.
- To explore the role of a rough glass surface (RGS) in mediating vesicle formation without additives.
- To assess the stability of the resulting STS vesicles under various conditions.
Main Methods:
- Utilized a solution of DTAB (dodecyltrimethylammonium bromide), a single-tailed surfactant.
- Employed a rough glass surface (RGS) as a mediator for vesicle formation.
- Investigated vesicle stability through long-term storage, high-temperature exposure, and freeze-thawing cycles after RGS removal.
Main Results:
- Spontaneous formation of novel vesicles from DTAB micelle solutions was observed, mediated by RGS.
- The obtained STS vesicles demonstrated significant stability.
- Vesicle stability was maintained after removal of the RGS, even after exposure to harsh conditions like high temperatures and freeze-thawing.
Conclusions:
- Rough glass surfaces can effectively mediate the spontaneous formation of stable single-tailed surfactant vesicles without requiring additional agents.
- The observed stability of these surfactant vesicles under various stress conditions highlights their potential for practical applications.
- This method offers a simplified and additive-free approach to vesicle synthesis.

Micelle formation is an intricate process that hinges on the properties of amphiphilic or amphipathic molecules and the conditions of the system in which they are found. Amphiphilic molecules, which have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts, play a critical role in this process.In aqueous environments, these molecules arrange themselves such that their hydrophilic heads are turned towards the water phase, while their hydrophobic tails are oriented away...

Surfactants, named for their behavior at interfaces, positively adsorb at the interfaces of two phases, reducing interfacial tension. Their versatility as emulsifiers, detergents, and foaming agents stems from this ability. Surfactants, often termed amphiphiles, share the property of amphipathy, with molecules having both hydrophilic and hydrophobic portions. The hydrophilic part is called the head, and the hydrophobic part, including an elongated alkyl substituent, forms the tail.Surfactants...

01:33Overview of Secretory Vesicles
8.8K
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Clathrin-coated vesicles use endocytosis to transport receptors and lysosomal hydrolases from the Golgi to the lysosome in the late secretory pathway. Clathrin-mediated endocytosis was the first described endocytic process, and Clathrin-coated vesicles remain one of the most well-studied transport vesicles. The molecular machinery that generates clathrin-coated vesicles comprises over 50 proteins that precisely coordinate vesicle formation. Cell surface receptors concentrated in indented sites...

4.0K
Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...
