General description
1-十八烷硫醇（ODT）是一种具有18碳烷基链的水溶性硫化合物，它与过渡金属（如金）形成强疏水性组装体，并在此类过渡金属表面形成自组装单层（SAM）。硫醇膜与金属电极表面共价键合时，显示出电致伸缩现象，导致电容变化。ODT SAM具有疏水表面，接触角为102oC。

The interactions of water, carbon dioxide, and Xe with octadecanethiol (C(18)H(37)SH, ODT) self-assembled monolayers (SAMs) were studied under ultrahigh vacuum conditions employing temperature-programmed desorption and optical diffraction measurements. The ODT layer was grown on a 1 nm thick gold film

Hybrid bilayer lipid membranes (HBMs) were built on roughened silver electrodes exhibiting surface-enhanced Raman scattering (SERS) activity. The HBM consisted of a first layer of octadecanethiol (ODT) directly bound to the electrode surface, on which a second layer of 1,2-diphytanoyl-sn-glycero-3-phosphocholine

Experiments that utilize structures generated by dip-pen nanolithography (DPN) as positive resists for fabricating nanohole arrays and lithographic masters are described. The technique takes advantage of the difference in desorption potentials for patterned structures made from 16-mercaptohexadecanoic acid (MHA) and
