Used extensively in bioconjugation and surface modification, it serves as a linker molecule to attach biomolecules like proteins, peptides, or antibodies to other substrates or nanoparticles. Its thiol group reacts with maleimide or gold surfaces, while the amine group enables further functionalization or cross-linking. In drug delivery systems, it enhances solubility and stability of therapeutic agents. It is also applied in the development of biosensors, where it aids in immobilizing biomolecules on sensor surfaces for improved detection. Additionally, it is utilized in the synthesis of hydrogels and polymers for tissue engineering and regenerative medicine due to its biocompatibility and ability to form stable bonds.
