Oligonucleotide Microarrays
Oligonucleotide microarrays are constructed either
by spotting prefabricated oligos on a glass support
[13] or by the more elegant method of direct in situ
oligo synthesis on the glass surface by photolithography
[28–30]. The strength of this approach lies in
its ability to discriminate DNA molecules based on
single base-pair difference. This allows the application
of this method to the fields of medical diagnos
