m-PEG10-amine is widely used in bioconjugation and drug delivery systems due to its ability to improve solubility, stability, and bioavailability of therapeutic compounds. It is commonly employed to modify peptides, proteins, and nanoparticles, enhancing their pharmacokinetic properties and reducing immunogenicity. In drug delivery, it acts as a linker to attach targeting moieties or therapeutic agents, enabling precise delivery to specific tissues or cells. Additionally, it is utilized in the development of hydrogels and biomaterials for tissue engineering, where it provides controlled release of bioactive molecules. Its hydrophilic PEG chain also helps in reducing non-specific interactions, making it valuable in diagnostic applications and biosensors.
