a Atomic force microscopy tapping mode image of thiol-modified oligonucleotides DPN patterned on a gold surface [86]. b Epifluorescence image of fluorophore-labeled DNA hybridised to a DPN-generated pattern of complementary oligonucleotides on an oxidised silicon surface [86]. c Combined red–green epifluorescence image of two different fluorophore-labeled sequences simultaneously hybridised to a two-sequence array deposited on an oxidised silicon surface by DPN [86]
