Applications
Cell Culture: Substrates are prepared in an electron beam evaporator that is solely dedicated to the deposition of gold films. This prevents the occurrence of impure metals contaminating the gold films, as is the case when multi-user equipment is used to coat gold substrates
Microarrays: Substrates are prepared in an electron beam evaporator using titanium, not chromium, as the adhesion layer. This avoids the contamination that can occur when a thin layer of chromium is used to promote adhesion of the gold film to an underlying substrate (such as a glass microscope slide), since chromium readily dissolves and diffuses to the surface of the gold film (and can adversely modify the reactivity of the gold).
Surface Plasmon Resonance: Substrates are deposited using an electron beam evaporator, which permits precise control of gold deposition rates and thus the surface roughness. This ensures a high level of control over the thickness and nanometer-scale surface roughness of gold films, as is necessary in order to generate reproducible results with surface plasmon resonance.
Scanning Probe Microscopy: Substrates deposited on mica can be thermally annealed or transferred to epoxy resin (reverse mounting) to form atomically flat surfaces suitable for scanning probe microscopy.
Benefits
- Plasma-Cleaned Surfaces: substrates cleaned prior to coating with an oxygen plasma
- Electron-Beam Deposited Metal Films: precise control of gold deposition onto substrates
- E-Beam Evaporator Dedicated to Ti/Au: no foreign metal contamination in gold films
- Pure Gold: 99.999% pure gold source used for coatings
- Titanium Adhesion Layers: less contamination of gold due to diffusion than with chromium
- Preparation in Clean Room: reduces exposure to particulates
- Quality Assurance: analysis via AFM, ellipsometry, goniometry, and spectrophotometry to validate quality
Gold-Coated Microscope Slides
Gold-Coated Microscope Slides are versatile and easy-to-use. Used for a wide range of applications such as cell culture, surface plasmon resonance (SPR), biosensors, electrochemistry, and electrochemical spectroscopy.
Gold-Coated Silicon Wafers
Gold-Coated Silicon Wafers are popular substrates for soft lithography, and for studies in Raman spectroscopy, Infrared (IR) spectroscopy. For example, researchers using PM-IRRAS techniques have studied water molecules adsorbed on gold.

Gold-Coated Silicon Chips
Template Stripped Gold Surfaces offer a clean, near atomically-flat surface that is ideal for applications in nanotechnology, such as studies on self-assembly, single-molecule imaging, nano- or micro-contact printing, DNA origami, or nano-photonics. For example, researchers use these surfaces to characterize self-assembled monolayers (SAMs) using atomic force microscopy (AFM), or scanning tunneling microscopy (STM).
• 99.999% gold purity
• RMS surface roughness near atomically flat
• Ultraclean gold surface does not required cleaning
• Surface is free from oxygen, organics and other atmospheric contaminants
• Ready to use when you need it
The chips are fabricated by coating the flattest available prime grade silicon wafers or freshly split mica. Then, 1-cm2 glass chips are epoxyglued to the gold film. The gold surface you use is the one in contact with the silicon or mica substrate, so it is ultra-flat and protected from the atmosphere until you are ready to use it.
