Gold (Au)
Gold is found as a free metal in nature, occurs in veins and alluvial deposits, and is associated with tellurides, quartz, and pyrite.
In pure form, it's an attractive metallic yellow color, but can be black, ruby, or purple in smaller quantities. As the most malleable and ductile metal, gold is typically alloyed for strength. It conducts heat and electricity, reflects infrared rays, and is mostly unaffected by air and chemicals. Some of gold's 18 isotopes are used in medicine to treat cancer and arthritis.

Platypus Technologies LLC Platypus Technologies UltraFlat Gold Films, Template Stripped Gold-Coated Glass on Silicon, 20 Glass Chips
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, 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. Platypus Ultra-Flat Gold Chips have a uniform film of gold that covers the entire surface area of the chip. Pristine gold surface with ultra-low RMS roughness approaching atomic flatness is ideal for Atomic Force Microscopy (AFM), tunneling microscopy, single-molecule studies, or studies of self-assembled monolayers (SAMs).
