Usage: technical; chemistry; biology

Examples

• Soap molecules in water form micellae that trap dirt and oil.
• The detergent's micellae help dissolve grease during washing.
• Researchers studied how micellae behave in different pH conditions.
• Micellae are essential structures in the digestion of fats in the small intestine.
• The size and stability of micellae depend on the concentration of surfactant.
