The Treatment of Breast Cancer Using Liposome Technology

Figure 2

Liposomes can accommodate both hydrophobic and hydrophilic drugs either in the phospholipid bilayer or in the internal aqueous core, respectively. They can be used in passive delivery of drugs or in active delivery in which targeting ligands are added. Targeting ligands are selected based on various upregulated cell-surface receptors present on cancer cells with respect to normal cells.
