UNCD Sensor Substrates
FAQs & How To’s
How to store the substrates?
Store in a dry vial at 25°C. Prefereably in an inert atmosphere.
How to clean the substrates?
Acid wash, electrochemical cleaning using 0.1 M sulphuric acid.
Can UNCD be polished?
Yes. It can be polished with alumina slurries similar to glassy carbon and sonicated in water.
Can UNCD be micro or nano-patterned?
Yes. A reactive ion etching (SF6/O2) recipe is provided in this “Diamond MEMS 101” guide which provides a Diamond Etch Recipe (see brochure at left)
