Self-Assembled Monolayers: Thiols
Surface Chemistry

Our thiols enhance the sensitivity, selectivity and specificity of chemically modified gold surfaces. An alkanethiol will stick to a gold surface and form an ordered assembly with the alkyl chains packing together. We currently offer Whitesides monothiols and aromatic-dithiols in 10mg quantities. Larger quantities are available upon request.

Common applications include chemical modification of surfaces used in:

• AFM (Atomic Force Microscopy)
  - chemically and biologically functionalized tips and substrates
• DPN (Dip-Pen Nanolithography)
• SPR (Surface Plasmon Resonance)
• QCM (Quartz Crystal Microbalance)
• Gold nanoparticles
• Surface-enhanced Raman Spectroscopy
• Electrochemical sensors
• Microcontact printing
• UV photopatterning
