A micelle (pronounced /maɪˈsɛl/ ("my sell") or /maɪˈsiːl/ ("my seal"), plural micelles, micella, or micellae) is an aggregate of surfactant molecules dispersed in a liquid colloid. A typical micelle in aqueous solution forms an aggregate with the hydrophilic "head" regions in contact with surrounding solvent, sequestering the hydrophobic single tail regions in the micelle centre. This phase is caused by the insufficient packing issues of single tailed lipids in a b… (More on Micelle)
