Used as a surface modifier in nanomaterial synthesis, particularly for stabilizing nanoparticles in aqueous solutions. Enhances dispersion and prevents aggregation due to its phosphate group and amine functionality. Applied in biomedical research for functionalizing silica-based particles, enabling conjugation with biomolecules like proteins and DNA. Also utilized in corrosion inhibition studies, where it forms protective layers on metal surfaces. Shows potential in gene delivery systems by assisting in the formation of stable polyplexes. Employed in the development of sensors and biosensors due to its ability to anchor recognition elements onto electrode surfaces.
