Detection of oligonucleotide sequences on diazonium modified silicon substrates through electrical impedance measurements
4-nitrobenzenediazonium modified silicon substrates were used in the detection of immobilized 20-mer homo-oligonucleotides through electrical impedance measurement. The silicon (100) and (111) substrates were functionalized with the diazonium through cyclic voltammetry and the nitro group was subseq...
