Liposomal drug delivery is a method that uses tiny spherical structures called liposomes to transport medications. These liposomes are made of lipid (fat) layers that can encapsulate drugs, protecting them from degradation and allowing for a controlled release in the body. This technique enhances the effectiveness of the drug while minimizing side effects. This delivery system is particularly useful for targeting specific tissues or cells, such as in cancer treatment. By modifying the liposome's surface, researchers can improve the targeting ability, ensuring that the drug reaches the intended site more efficiently, which can lead to better therapeutic outcomes.
