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。
Application
ODT用于将硫醇化分子沉积到金基质的表面上，例如
- 金石英晶体谐振器上的SAM。
- 在原子力显微镜探针的尖端。
- 电容式传感器。

To make ultrathin films for the fabrication of artificial olfactory systems, odorant biosensors, we have investigated mixed Langmuir and Langmuir-Blodgett films of odorant-binding protein/amphiphile. Under optimized experimental conditions (phosphate buffer solution, pH 7.5, OBP-1F concentration of 4 mg L(-1), target
