“…In aqueous media most of these molecules, with or without the participation of lipids such as phospholipids and/or cholesterol, form vesicles, known as metallosomes [15][16][17][18]. If the metallosurfactant contains a transition metal bonded to some CO ligands, either in the hydrophilic or in the hydrophobic domain, then a metallosome with CO releasing properties can be obtained [19,20].…”
