This chemical is primarily used in bioconjugation and surface modification applications. Its DBCO (dibenzocyclooctyne) group enables click chemistry reactions, particularly with azide-containing molecules, making it valuable for labeling, imaging, and drug delivery systems. The PEG4 spacer enhances solubility and reduces steric hindrance, improving reaction efficiency. The triethoxysilane moiety allows for covalent attachment to silica-based surfaces, such as glass or nanoparticles, facilitating the creation of functionalized materials for biosensors, diagnostics, and targeted therapies. Its versatility makes it a key tool in nanotechnology, biomaterials, and biomedical research.
