You can now conveniently functionalize the gold-coated surfaces for which Platypus is known using Platypus' Functionalization Kits.
Features enable you to:
Each Functionalization Kit contains:
Convenience
The chemicals and gold-coated surfaces are provided, along with instructions on how to functionalize the gold.
Simplicity
In a few simple steps, you can have chemically functionalized gold-coated substrates of your choice.
Simple instructions are provided with each kit.
Quality
Platypus Technologies is known for quality. We stand behind our products with an unconditional satisfaction guarantee.
Affordability
Custom synthesized chemicals are expensive and must often be purchased in bulk.
Platypus Kits provide smaller quantities of chemicals to eliminate prohibitive start-up costs.
Technical Support
Experienced PhD scientists and engineers are available to answer any technical questions.
Compatibility
Functionalized gold films may be used with a variety of patterning techniques
such as microcontact printing, dip-pen nanolithography (DPN) and photoimmobilization
Advantages to functionalizing a gold surface instead of a plain glass surface:

Further tips for the attachment of DNA:
A typical protocol is to prepare the
NH2-terminated self-assembled monolayer first, introduce the NHS-maleimide crosslinker and then immobilize the
thiolated DNA to the SAM through thiol-maleimide coupling. The following two papers discuss how to immobilize
thiolated DNA to SAMS:
Robert Corn etc., JACS, 1999, 121, 8044-8051.
O'Ferrall etc., Nucleic Acid Research, 1996, 24, 3031-3039.
