MAC-PEG-MAC is widely used in biomedical applications due to its unique properties. It serves as a versatile crosslinker in the development of hydrogels, which are essential for drug delivery systems, tissue engineering, and wound healing. Its amphiphilic nature allows it to form micelles or nanoparticles, making it suitable for encapsulating and delivering hydrophobic drugs. Additionally, it is utilized in surface modification to enhance biocompatibility of medical devices and implants. The PEG segment provides flexibility and reduces immunogenicity, while the MAC groups enable covalent bonding with biomolecules or surfaces, ensuring stability in various biological environments.
