This chemical is widely used in the formulation of lipid nanoparticles, particularly in drug delivery systems. Its amphiphilic nature allows it to stabilize liposomes and other lipid-based carriers, enhancing their biocompatibility and circulation time in the body. It is a key component in the development of mRNA vaccines, where it helps encapsulate and protect the mRNA, ensuring efficient delivery to target cells. Additionally, it is employed in the creation of stealth liposomes, which evade the immune system and improve the therapeutic efficacy of encapsulated drugs. Its application extends to cancer therapy, where it aids in the targeted delivery of chemotherapeutic agents, reducing off-target effects and improving patient outcomes.
