Description and Uses
ODT is used in the surface modification of gold nanoparticle (AuNPs)/Nickel (Ni) foam conjugate for the preparation of a 3D surface enhanced Raman spectroscopy(SERS) substrate for the detection of organic pollutants. It may also be used enhance the superhydrophobic properties for different materials like nano-sized copper films, graphene and silica for different applications like mercury detection and electrochemical analysis.
