General description

1-Octadecanethiol (ODT) is an alkanethiol with a long carbon chain mainly used as a self-assembled monolayer (SAM) for surface modification of a wide range of materials. It facilitates superhydrophobicity with high wettability and low surface energy.

Application

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.

Micro and Nanometer Scale Photopatterning of Self-Assembled Monolayers

Self-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold).

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
