Used in biomedical research as a model for studying polypeptide interactions and self-assembly due to its amphiphilic nature. It is applied in drug delivery systems for encapsulating and releasing therapeutic agents, leveraging its ability to form micelles or vesicles. Also utilized in tissue engineering scaffolds to promote cell adhesion and growth. Its cationic properties make it suitable for gene delivery, facilitating the binding and transport of nucleic acids. Additionally, it serves as a substrate for enzymatic studies to understand protease activity and specificity.
