Used primarily in the field of surface chemistry and nanotechnology, it serves as a key component in the formation of self-assembled monolayers (SAMs) on gold and other noble metals. These SAMs are crucial for modifying surface properties, enabling applications in biosensors, molecular electronics, and corrosion inhibition. It also acts as a linker molecule in the immobilization of biomolecules, such as proteins and DNA, onto surfaces for diagnostic and research purposes. Additionally, its thiol group allows for strong binding to metal surfaces, making it valuable in creating functionalized nanoparticles for targeted drug delivery and imaging in biomedical applications.
