NanoBio: Cleaning SiO2 surfaces


 * Cleaning SiO2 surfaces
 * 1) Load coverslips into ceramic holder.
 * 2) Immerse in heated 20% 7x detergent for 5 minutes.
 * 3) Rinse coverslips thoroughly for 5 minutes with double distilled water.
 * 4) Dry the coverslips with N2(g).
 * 5) Cleaning surfaces for supported bilayer formation
 * 6) Expose to air plasma for 3 min. using Harrick plasma cleaner in Rm 1201.
 * Note:Do not place colloidal gold or PDMS (polydimethylsiloxane) in the plasma cleaner. This will contaminate the chamber and other people’s samples. If you want to plasma clean a sample that contains these materials, please talk to Paul Ashby about using a separate glass chamber
 * Note:Contact Paul Ashby for safety training in order to gain access to Rm1201.
 * 1) Close the needle valve.
 * 2) Hold the lid on the chamber.
 * 3) Turn on the pump.
 * 4) Open the needle valve so that you stably maintain a pressure of 100-140 mTorr.
 * 5) Turn on the power to the chamber.
 * 6) For SiO2, turn the power setting to high for 3 min. The chamber should glow purple with a hint of white.
 * 7) Turn off the pump.
 * 8) Watch the pressure gauge. When it reaches 1 torr, slowly open the valve until the lid pops off.
