Used in bioconjugation and drug delivery systems, it serves as a linker to attach bioactive molecules to polymers or nanoparticles. Its hydrophilic PEG spacer enhances solubility and reduces immunogenicity. Commonly applied in the development of antibody-drug conjugates (ADCs) and targeted therapies. Also utilized in hydrogel formulations for controlled drug release and tissue engineering scaffolds. Its reactive acryloyl group allows for crosslinking in photopolymerization processes, making it suitable for 3D bioprinting and biomedical coatings.
