In this paper, we propose to electrochemically transform the alkaline polyelectrolyte solution of DNA into DNA nanospheres (EsDNA). The result showed that stable DNA nanospheres for at least two months at 4 OC were successfully electro synthesized. UV-visible spectra of the prepared nanospheres revealed an emerged peak ranged from 372-392 nm depending on the DNA concentration and from 361 to 398.3 nm depending on electrospherization time. This result confirmed with size distribution curves figured out from TEM images, introduced that with increasing electrospherization time (6, 12 and 24 hrs.) induces a growing in the average size of DNA nanospheres (48, 65.5 and 117 nm, respectively). In addition, it introduced that the average size of DNA nanospheres become larger (37.8, 48 and 76.5 nm) with increasing DNA concentration (0.05, 0.1 and 0.2 wt.%) respectively. Also, our resns.The magnetotransport properties of a hybrid InSe/monolayer graphene in a SiC system are systematically studied. Compared to those of its bare graphene counterpart, in InSe/graphene, we can effectively modify the carrier density, mobility, effective mass, and electron-electron (e-e) interactions enhanced by weak disorder. We show that in bare graphene and hybrid InSe/graphene systems, the logarithmic temperature (lnT) dependence of the Hall slope R H = δR xy /δB = δρ xy /δB can be used to probe e-e interaction effects at various temperatures even when the measured resistivity does not show a lnT dependence due to strong electron-phonon scattering. Nevertheless, one needs to be certain that the change of R H is not caused by an increase of the carrier density by checking the magnetic field position of the longitudinal resistivity minimum at different temperatures.
