Used primarily in bioconjugation and surface modification, this compound is valuable for attaching biomolecules to surfaces or nanoparticles. Its triethoxysilane group allows it to form stable bonds with glass, silica, or metal oxide surfaces, while the TCO group enables efficient click chemistry reactions with tetrazine-modified molecules. This makes it ideal for creating functionalized materials in drug delivery systems, biosensors, and diagnostic tools. Additionally, the PEG spacer enhances solubility and reduces non-specific interactions, improving biocompatibility in biomedical applications.
