Microarray technology is a rapidly developing field and a powerful tool in genome and
proteome analysis and drug screening.[1–4] Although several types of microarrays of
oligonucleotides and peptides have been constructed, surface patterning methods are still a
key challenge in the field of 'biochip'fabrication. Self-assembled monolayers (SAMs) of
alkanethiols on gold surfaces are widely used in nanotechnology and serve as templates for
the immobilization of biomolecules.[5] UV lithography is a well-established patterning …
