XPS measurements of the electrochemical removal of an oligonucleotide functionalization layer on the gold sample. X-Ray Photoelectron Spectroscopy (XPS) data are shown for the Au4f, N1s and P2p peaks for oligonucleotide functionalized (A) and electrochemical cleaned (B) gold samples. A clear increase in the gold peak as well as a clear removal of the phosphate peak of the cleaned sample can be seen.
