This compound is primarily used in the field of nanotechnology and materials science, particularly for surface modification and self-assembled monolayers (SAMs). Its long polyether chain and thiol group make it highly effective for creating well-ordered, stable monolayers on gold and other noble metal surfaces. These monolayers are essential in applications such as biosensors, where they provide a biocompatible interface for immobilizing biomolecules like proteins or DNA. Additionally, it is utilized in the development of anti-fouling coatings, which prevent unwanted adhesion of proteins, cells, or bacteria on surfaces, making it valuable in medical devices and marine applications. Its ability to form precise molecular structures also aids in the fabrication of nanoscale electronic devices and molecular electronics.
