Short DNA sequences (21 monomer units) from the Escherichia coli pathogen, modified with a inorganic phosphate grouping at the 5′ end, were bespoken to the bound of the conductor done the affinity of the salt group for zirconia, to make an effective DNA exploration (ss DNA/Zr O/SPE). DNA preservation and crossbreeding were defined using differential pulse voltammetry by employing methylene dejected as oxidation-reduction indicator. mark sequences hybridized with the examine resulted in a decrease of the reaction peak current of group dispirited intercalated into the probe.
