Screen-printed gold electrodes were, firstly, modified with a mixed monolayer of a 25-mer thiol-tethered DNA probe and a spacer thiol, 6-mercapto-1 -hexanol (MCH). The DNA probe sequence was internal to the sequence of the 35S promoter, which sequence is inserted in the genome of GMOs regulating tire transgene expression. [Pg.15]

In some cases the cyclic voltamogram itself recorded when ramping the electrode potential as described above shows a characteristic minimum around iipzc (e.g. with single crystal gold electrodes [86Kol, 96Ham2]) (Data obtained with this method are labelled CV). [Pg.183]

Based on the experimental conditions the gold electrode is most likely covered with underpotential deposited (upd) silver. Consequently the value of iip c should be compared with the corresponding value for a silver electrode. [Pg.441]

Coulomb blockade effects have been observed in a tunnel diode architectme consisting of an aluminum electrode covered by a six-layer LB film of eicosanoic acid, a layer of 3.8-nm CdSe nanoparticles capped with hexanethiol, and a gold electrode [166]. The LB film serves as a tunneling barrier between aluminum and the conduction band of the CdSe particles. The conductance versus applied voltage showed an onset of current flow near 0.7 V. The curve shows some small peaks as the current first rises that were attributed to surface states. The data could be fit using a tunneling model integrated between the bottom of the conduction band of the particles and the Fermi level of the aluminum electrode. [Pg.89]

A somewhat similar approach has been nsed for the formation of nanosize wires stretching between gold electrodes [34]. Lambda-DNA was positioned between two electrodes, with immobilized oligonncleotides complementary to lambda-DNA sticky ends. Silver (Ag ) ions were deposited on the stretched DNA bridges, followed by rednction of absorbed ions to metallic silver with hydroquinone. The resulting silver clusters formed on DNA strands were found to be 100 nm in diameter and were capable of condncting the electric current. [Pg.435]
