SuperGold Substrates


SuperGold Microarray Substrates provide a superior 500-angstrom gold layer surface for microarray surface plasmon resonance, nanotechnology, electrochemistry, biosensors, and other high-end applications. The manufacturing process begins with our atomically flat (SuperClean) polished glass as the substrate and constructs the 500 Å gold layer using an ultra-durable chrome adhesion layer attachment approach. The SuperGold K series provides a 1000-angstrom gold layer surface for specialized applications.

Congratulations on taking a big step towards improving your microarray and advanced technology research. This booklet contains complete protocols outlining the steps required to use ArrayIt® SuperGold Microarray Substrates.

Quality Control

ArrayIt® takes every measure to assure the quality of our SuperGold Microarray Substrates. Rigorous quality control monitoring on a substrate-by-substrate basis guarantees that these products conforms to the highest industry standards.

Product Description

ArrayIt® provides the world’s only gold substrate on an atomically flat glass surface. Our innovative, high-end SuperGold Substrates make gold-surface based assays rapid, affordable, easy to implement, and the data obtained will be superior to other products in the field. Users will appreciate the following features:

  • 500 Å layer of pure gold for superior performance
  • 1000 Å layer thickness available in the SuperGold K series
  • Microarray, cell biology, nanotechnology, SPR, microscopy and other applications
  • Atomically flat glass substrate improves assay precision
  • Chrome adhesion method provides superior durability
  • Cleanroom manufacturing process prevents particle contamination
  • More convenient and better quality than “home made” surfaces
  • Antistatic, environmental proof packaging
  • Corner chamfer for unambiguous gold (functional) side identification
  • Substrates arrive ready to use

Figure 1.  SuperGold Microarray Substrate in a class 100 cleanroom. The 500 Å gold layer on the atomically flat glass substrate is readily visible. The SMG5 product is manufactured and packaged in a cleanroom environment, and is provided in boxes of 5 pieces for affordability and ease-of-use. Make sure to use the top (gold) side of the substrate only.  The gold is deposited on the side corresponding to the cropped (chamfer) located in the upper right of the substrate as shown in the photograph.
