Micelles are formed by self-assembly of amphiphilic molecules. The structures contain hydrophilic/polar [water loving] region (head) and hydrophobic/nonpolar [water hating] region (tail). Micelles are formed in an aqueous solution whereby the polar [water soluble] region faces the outside surface of the micelle and the nonpolar [fat soluble] region forms the core. Micelles can deliver both hydrophilic and hydrophobic agents.
