Piranah effect on Au
Edward Keough

Hello,

Does anyone have any information on piranah's (30% H2O2 : 70% H2SO4)
effect on a 100nm Au layer on silica. Piranah is volently active, it
completely removes my Au layer, but I have seen in literature it can be
used to clean Au. I am trying to drive off organic contaminants and
make my silica hydrophilic using piranha solution while keeping my Au
layer in some areas.

I appreciate any information, thank you.
