“…Similarly, Saebnoori et al [96] have observed that solutions with lower concentrations of potassium carbonate exhibit lower current density and higher breakdown voltage due to the lower conductivity of the electrolyte. Anbouri et al [86] have also shown that the same is true for glowdischarge electrolysis. For insulating liquids such as Milli-Q water, heptane, or liquid nitrogen, Belmonte et al [97] demonstrated, using a nanosecond-pulsed electrical switch, that discharges ignite at breakdown voltages beyond a few kV in micro-gaps and generate currents around hundreds of amps without a ballast resistor.…”

“…In glow-discharge electrolysis, Anbouri et al [86] showed that size evolution can vary depending on the electrolyte. With a higher concentration of K2CO3, and thus higher conductivity, the size of copper nanoparticles increases, but it decreases in NaOH.…”

“…Anbouri et al [86] observed in glow-discharge electrolysis that the size of copper nanoparticles increases as the concentration of K2CO3 increases from 0 to 1M. In contrast, it decreases when NaOH concentration, used instead of K2CO3, increases also from 0 to 1M.…”

Electrical discharges in liquids are used to synthesize and process nanoobjects with breakthrough achievements that lead to high expectations in the field. As plasmas are non-equilibrium media, the possibility to access novel compositions, shapes, structures, etc. is often put forward as major argument to promote these processes. Two main classes of processes are considered in this review: the so-called "solution plasma" and glow-discharge electrolysis. The influence of the main parameters controlling the selected processes is discussed. Applications are also presented together with expectations on breakthrough achievements awaited for these processes. Solution characteristics Electrical conductivityElectrical conductivity is generally the key factor that determines the applied voltage required for breakdown and discharge ignition. The lower the conductivity, the higher the voltage needed to achieve reproducible discharges, and the shorter the pulse width.

“…Effect of DNA concentration. Concentration of the electrolyte is one of the many variables that may have a direct impact on the features of nanospheres by tuning their size and morphology[58,59].Considering the effect of DNA concentration (0.02, 0.05, 0.1, 0.15 and 0.2 wt%) on the prepared spheres, the UV-vis absorption spectra were measured, as shown in figures 5(a)-(e). It was found that the spectral peak absorbance and location depend on the concentration of DNA in the electrolyte (figure 5(f)).…”

We describe new method for preparing DNA nanospheres for a self-assembled atenolol@DNA (core/shell) drug delivery system. In this paper, we propose the electrochemical transformation of an alkaline polyelectrolyte solution of DNA into DNA nanospheres. We successfully electrosynthesized DNA nanospheres that were stable for at least 2 months at 4 °C. UV–visible spectra of the prepared nanospheres revealed a peak ranging from 372 to 392 nm depending on the DNA concentration and from 361 to 398.3 nm depending on the electrospherization time. This result, confirmed with size distribution curves worked out from transmission electron microscopy (TEM) images, showed that increasing electrospherization time (6, 12 and 24 h) induces an increase in the average size of DNA nanospheres (48, 65.5 and 117 nm, respectively). In addition, the average size of DNA nanospheres becomes larger (37.8, 48 and 76.5 nm) with increasing DNA concentration (0.05, 0.1 and 0.2 wt%, respectively). Also, the affinity of DNA chains for the surrounding solvent molecules changed from favorable to bad with concomitant extreme reduction in the zeta potential from −31 mV to −17 mV. Principally, the attractive and hydrophobic interactions tend to compact the DNA chain into a globule, as confirmed by Fourier transform infrared spectroscopy (FTIR) and TEM. To advance possible applications, we successfully electro self-assembled an atenolol@DNA drug delivery system. Our findings showed that electrospherization as a cost–benefit technique could be effectively employed for sustained drug release. This delivery system achieved a high entrapment efficiency of 68.03 ± 2.7% and a moderate drug-loading efficiency of 3.73%. The FTIR spectra verified the absence of any chemical interaction between the drug and the DNA during the electrospherization process. X-ray diffraction analysis indicated noteworthy lessening in atenolol crystallinity. The present findings could aid the effectiveness of electrospherized DNA for use in various other pharmaceutical and biomedical applications.

This research aims to study the effects of the manipulation of the concentration of electrolyte on the synthesis and size control of carbon nanoparticles. Submerged glow-discharge plasma (SGDP) method was used which is a type of electrolysis. This method was proven to be both cost effective and eco-friendly in the synthesis of nanoparticles. Carbon nanoparticles generally range from 1 to 100nm and its small size gives it a high surface area to low volume ratio which gives it an edge over the sheet and bulk metals. They vary in their mechanical properties with respect to their sizes which makes it ideal for the manufacturing industry. The ability to control carbon nanoparticle size will give manufacturers the ability to obtain the desired mechanical properties. This research brings the potential of being able to control the size of carbon nanoparticles with a simple and cost-effective method by changing the concentration of electrolyte and plasma discharge voltage. The manufacturing industry in the future can benefit from this research as they will be able to manufacture materials with better mechanical properties at a cheaper cost.
