High Quality Gold (Au) Thin Films on Substrates

To better serve you, we would like to discuss your specific requirement, Please Contact Us for a quote.

MSE Supplies offers High Quality Gold (Au) Thin Films with a variety of thickness and substrates. We use 99.999% pure gold and titanium in our coating process, and coat only those substrates that are stable under high vacuum. This eliminates concerns about contamination from previous coating runs.

Applications include:

  • Sensors & Microarrays: Chromium-free gold films are the best option for preserving surface reactivity when you want to create self-assembled monolayers for sensor development and for attachment of bioactive probe molecules.
  • Scanning Probe Microscopy: To minimize surface roughness, consider our ultra-flat template-stripped gold (reverse mounted) glass chips, available mounted on silicon or mica.
  • Mirrors: For efficient reflection/total internal reflection systems in optical instruments
  • Cell Culture: We use of only pure metals in our coater avoids contamination with traces of other metals or chemicals that may be toxic to cultured cells. If you are having difficulty culturing cells on gold films made in coaters used by others, consider using the highest purity gold films from us.
  • Surface Plasmon Resonance: The coating process permits precise control of gold deposition rates and thus surface roughness. This ensures the highest level of control over the thickness and nanometer-scale flatness of gold films, for the best possible surface plasmon resonance responses. Call us for details on how we can help you optimize your SPR performance.

    Features of our coating process include:

    • 99.999% Pure gold
    • Plasma-cleaned surfaces
    • Electron-beam deposited gold films
    • Optional titanium adhesion layer
    • Dedicated cleanroom fabrication environment
    • Strict quality control measurements
