The piranha solution
WebbPiranha solution (H 2 O 2 /H 2 SO 4 mixed in a 1:1 ratio) is strongly oxidizing with a similar mechanism of action as Argon plasma, with the exception that the surface functionalization is more strictly confined to the outer regions and tips of surface microstructures of the foam in contact with the solution. WebbPiranha solution should only be used when less aggressive cleaning methods fail. All persons working with Piranha solution must be aware of the hazards, know the details of this SOP and be trained in proper use, disposal, and emergency procedures.
