Platypus provides customized SPR chips for your individual SPR needs. We can acquire high-grade optical glass per your specifications, coat it with your specific Ti and Au thicknesses, and cut it down to the size you need.
GOLD-COATED SUBSTRATESPlatypus offers gold-coated glass slides, mica, silicon wafers, and coverslips.
TEMPLATE STRIPPED GOLD CHIPSPlatypus® Template Stripped Gold Chips provide an extremely smooth and clean gold surface for a variety of research needs, including AFM and SEM applications, biosensor development, and SAMs studies. Immediately before use, simply strip a chip (1cm x 1cm) from a gold-coated templating surface. Choose between chips stripped from a gold-coated atomically flat, cleaved mica template or chips stripped from a gold-coated prime grade silicon wafer template. Unlike epitaxially grown or flame annealed atomically flat Au (111) terraces that are smooth over minute surface areas (< 2 um2), Platypus® Template Stripped Gold Chips have an ultraflat, thin film of gold that covers the entire surface area of the chip.
CUSTOM COATING PROJECTSPlatypus Technologies can produce customized Gold and/or Titanium coatings for biological, chemical, engineering, electrical and materials science applications. We can coat your own substrates, or we can coat our substrates according to your specifications.
NANO-PATTERNED POLYURETHANE SUBSTRATESPolymeric substrates are optically transparent and possess an anisotropic topography on tens of nanometer scales. The substrates are also available with conformal coatings of gold. When combined with the use of self-assembled monolayers formed from organosulfur compounds, these gold-coated polymeric substrates offer control of the chemical functionality and nanometer-scale topography of surfaces. This characteristic makes these substrates potentially useful in investigating a range of surface-dominated phenomena.
CONTACT PRINTING STAMPSPlatypus® Contact Printing Stamps offer the choice of planar, micro- or nano-patterned PDMS stamps.
