Claim:
1. An array of DNA molecules on a substrate comprising: a substrate that has a surface wherein the surface comprises regions wherein the regions comprise electrodes that have a surface and wherein at least one region comprises a plurality of DNA polymers that are attached to the surface of an electrode, wherein at least one of the regions comprises DNA polymers that comprise a first DNA polymer that comprises a first known sequence and a second DNA polymer that comprises a second known sequence and the first known sequence is different from the second known sequence, wherein the first DNA and the second DNA polymer are attached to the electrode surface through one trifunctional linker molecule, wherein the trifunctional linker molecule has three sites for attachment and wherein a first of the two DNA polymers is attached to one of the three sites, a second of the two DNA polymers is attached to a second of the three sites, and a third site is attached to the surface of the electrode.
