MAC-PEG-MAC finds its primary application in the field of drug delivery systems. It is widely used to create biocompatible and biodegradable hydrogels that can encapsulate and release therapeutic agents in a controlled manner. This makes it particularly valuable in targeted cancer therapies, where it helps in delivering drugs directly to tumor sites while minimizing systemic toxicity. Additionally, it is employed in tissue engineering as a scaffold material, providing a supportive structure for cell growth and tissue regeneration. Its ability to form stable, water-soluble polymers also makes it useful in creating coatings for medical devices, enhancing their biocompatibility and reducing the risk of adverse reactions.
