Compositions, methods and devices for generating nanotubes on a surface
First Claim
1. A method for modifying a surface by generating nanotubes at one or more selected sites on the surface, the surface comprising a first metal, the method comprising:
- positioning at least one cathode and at least one anode relative to the surface in an electrolyte solution comprising a fluoride salt of a second metal; and
applying a voltage between the at least one anode and the at least one cathode sufficient to generate nanotubes at one or more selected sites on the surface by removing a portion of the first metal from the surface by etching, and to inhibit nanotube formation at one or more of the other selected sites, wherein the nanotubes comprise the first metal and the second metal;
wherein the electrolyte solution comprises AgF or CaF2.

Abstract
A method for modifying a surface by generating nanotubes at one or more selected sites on the surface, the surface including a first metal. The method includes the steps of positioning at least one cathode and at least one anode relative to the surface in an electrolyte solution including a fluoride salt of a second metal, and applying a voltage between the at least one anode and the at least one cathode sufficient to generate nanotubes at one or more selected sites on the surface and to inhibit nanotube formation at one or more of the other selected sites, wherein the nanotubes include the first metal and the second metal.
