Abstract

A method of treating a material on a probe is provided. The method includes the steps of immersing a probe tip into a first fluid, wherein the probe tip includes one or more oxidized metallic fragments on a surface of the probe tip; polarizing the probe tip, through a counter electrode, with a negative current to reduce the one or more oxidized metallic fragments to one or more substantially unoxidized metallic fragments; removing the probe tip from the first fluid; immersing the probe in a second fluid, wherein the second fluid is a complexer for the one or more substantially unoxidized metallic fragments; and polarizing the probe tip with a positive current, through the counter electrode, wherein the positive current oxidizes the one or more substantially unoxidized metallic fragments.
