The comparison of deoxyguanosine (dGuo) and deoxyadenosine (dAdo) signals in pH four.70 acetate buffer (AB) by The impact of metal nanoparticles around the voltammetric signals of dsDNA bases was differential pulse voltammetry (DPV) at different modified electrodes.3.two. Optimization of Modified ElectrodesElectrode dsDNA/SPE dsDNA/PtNPs/SPE dsDNA/AgNPs/SPE dsDNA/PtNPs/AgNPs (monolayer)/SPE dsDNA/PtNPs/AgNPs (twolayer)/SPEexamined. The layerbylayer modification tactic was evaluated for preparing the nano dGuo dAdo biosensor. The PtNPs/AgNPs/SPE sensor was ready by dropping the optimum volume of 1 L PtNPs after which twostep of 5 L AgNPs.

On bare SPE, the As observed in Figure two, the oxidation signals of dGuo and dAdo had been obtained greater peaks of dGuo and dAdo appeared at 0.764 V and 1.014 V, respectively. Compared with at dsDNA/PtNPs/AgNPs/SPE, which was selected for further research. On bare SPE, the the PtNPs/AgNPs/SPE, the peak potentials of dsDNA bases were shifted to a less constructive peaks of dGuo and dAdo appeared at 0.764 V and 1.014 V, respectively. Compared with potential. It can be concluded that the metal nanoparticles modification technique showed the the PtNPs/AgNPs/SPE, the peak potentials of dsDNA bases had been shifted to a significantly less optimistic electrocatalytic impact. possible. It can be concluded that the metal nanoparticl.
