Our cell membranes are both lipid soluble and lipid loving. Their bilayered lipid membranes form a highly active skin that is constantly interacting with the internal and external environment, ferrying in nutrients and releasing waste. Liposomes, in turn, are microscopic phospholipid bubbles with a bilayered membrane structure that is similar to our cells. They are already widely used in the pharmaceutical industry to improve efficacy and safety of anticancer drugs, antifungal drugs, and anaesthetics. In fact, Mother Nature loves them, too. A 2000 study found that liposomes are naturally present in breast milk. [1]
