Used in gene delivery systems due to its ability to form polyplexes with DNA and RNA, enabling efficient cellular uptake. Its proton sponge effect facilitates endosomal escape, making it effective in non-viral vector applications. Commonly employed in biomedical research for transfection in vitro. Also utilized in stimuli-responsive drug delivery systems, where pH changes trigger release. Applied in surface coatings for medical devices to improve biocompatibility and enable controlled binding of biomolecules. Investigated for use in wound healing materials due to its interaction with cells and proteins.
