Poly(ethylene glycol) monomethyl ether acrylate (mPEG-acrylate) possesses hydrophobic properties and high solubility, making it suitable for the preparation of core-shell structured microcapsules for sustained or controlled drug release. It can be used to develop highly biocompatible materials with significant applications in drug delivery, gene therapy, and tissue engineering.
mPEG-acrylate can also be used to modify material surfaces through methods such as copolymerization and cross-linking, helping alter their physicochemical properties and biocompatibility. In addition, it can be copolymerized with other monomers to synthesize polymers with specific functionalities, including antimicrobial activity, degradability, and photosensitivity, for applications in materials science and biomedical engineering.
