Ultra-Flat Gold Films: Platypus® Template Stripped Gold Chips

Clean and UltraFlat Gold Surfaces Every Time

Template-Stripped Gold Chips provide an ultra-flat pristine gold surface for research applications including AFM and SEM, biosensor development, and studies of self-assembled monolayers. The chips are fabricated by coating the flattest available prime grade silicon wafers or freshly-split mica, with no adhesion layer. Then, 1cmx1cm square glass chips are epoxy-glued to the surface. 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.

Unlike epitaxially-grown or flame-annealed atomically flat Au(111) terraces that are smooth over very small areas (< 2 µm2), Platypus Ultra-Flat Gold Chips have a uniform film of gold (Au(111)) that covers the entire surface area of the chip.

Features & Benefits:

  • RMS roughness approaching atomic flatness.
  • Uncontaminated Surface – Gold is protected from the atmosphere until stripped from the template, providing a pristine surface free from organics and other atmospheric contaminants.
  • Ready to Use – Chips do not require cleaning, eliminating the need for hazardous cleaning solutions or expensive cleaning equipment.
  • Convenient – Multiple chips per template make it easy to prepare fresh, clean, and ultraflat chips just seconds before your next experiment.

Comparison with Standard Gold

Standard and ultra-flat gold surfaces were analyzed by Atomic Force Microscopy over a randomly-selected 1 µm2 area to assess roughness:
Ultra-Flat Gold Films vs Standard Gold


Ultra-flat gold surfaces enable high-resolution characterization of single molecules and self-assembled monolayers (SAM) via atomic force microscopy (AFM) or scanning tunneling microscopy (STM).  Ultra-flat gold surfaces are ideal for applications in self-assembly, single-molecule imaging, nano-contact printing, DNA origami, or nano-photonics.
