Micelle
Micelle — An aggregate of surfactant molecules in aqueous solution, forming a structure used in peptide solubilization and drug delivery.
What Is a Micelle?
A micelle is a spherical aggregate formed by amphiphilic molecules in aqueous solution, with hydrophobic tails oriented inward and hydrophilic heads facing water. Peptide amphiphiles form micelles above their critical micelle concentration (CMC), creating nanostructures for drug delivery and self-assembly research.
Applications
- Drug encapsulation: Hydrophobic drugs loaded in micelle core. 10-100 nm diameter
- Peptide amphiphiles: Lipid-tail peptides self-assemble into cylindrical micelles (nanofibers) or spherical micelles
- Detergent micelles: Solubilize membrane proteins/peptides for structural studies
