font size="1" face="AdvP497E2"> The adsorption and electrooxidation of nucleic acids on glassy carbon electrodes are evaluated by using chronopotentiometric stripping analysis. The influence of electrochemical pretreatments, supporting electrolyte, halides and monovalent cations levels as well as the role of the oligonucleotide length and composition, accumulation potential and time on the adsorption and further electrooxidation of oligo(dG)
