Amino-PEG6-amine is widely used in bioconjugation and drug delivery applications due to its dual amine functional groups and polyethylene glycol (PEG) spacer. The PEG chain enhances solubility, reduces immunogenicity, and improves the stability of conjugated molecules, making it ideal for modifying peptides, proteins, and other biomolecules. In drug delivery systems, it serves as a linker to attach targeting ligands or therapeutic agents, ensuring controlled release and improved pharmacokinetics. Additionally, it is utilized in the development of biosensors and diagnostic tools, where it facilitates the immobilization of biomolecules on surfaces while maintaining their activity. Its biocompatibility and water solubility make it a valuable component in nanotechnology and materials science for creating functionalized nanoparticles and hydrogels.
