Tri(amino-peg5-amide)-amine is widely used in bioconjugation and drug delivery systems due to its PEGylated structure, which enhances solubility and biocompatibility. It serves as a linker in the development of targeted therapeutics, enabling the attachment of drugs, peptides, or antibodies to improve specificity and reduce off-target effects. Additionally, it is utilized in the creation of hydrogels and biomaterials for tissue engineering, where its ability to form stable, flexible networks supports cell growth and regeneration. Its application also extends to diagnostics, where it is employed in the design of imaging agents and biosensors for enhanced detection and accuracy.
